Many gamblers may be familiar with the classic game of keno. This is basically a lottery-style game in which players select a few numbers and then see several numbers drawn. Keno players are hoping that their own numbers hit – rewarding them a nice payout in the process. Slot machines also feature random results and keno slot machines combine these traditional games – greatly speeding up the keno action in the process. These games can be found in many casinos around the world and offer an alternative to traditional slot play. Keep reading to learn more about keno slot machines as well as the history and mechanics behind classic keno. 1 – How to Play Keno Slot Machines Most casinos offer players the relaxed gaming environment of playing keno. In a typical game, players select up to 15 numbers on a keno card among a total of 80 available numbers. Players usually use a dabber or crayon to make their selections. Here are two key terms players will find when playing some keno. Spot – These are the numbers a player select on their keno cards. The classic version of the game is also called “spot keno” at some casinos. Catch – This is the term used to describe spots that match numbers that are drawn. The goal is to “catch” as many numbers as possible to maximize winnings. Once the selection time has passed, random numbers are then produced from a keno hopper. Players then watch a screen showing all the numbers and highlighting the winning picks. Payouts are based on the number of selections made, the amount bet, and the total spots that hit when numbers are drawn. The game’s pay table shows how much is paid out for catching numbers and these vary by casino. There aren’t a ton of bells and whistles to the classic game of keno, although some alternative versions found on keno slots feature additional balls, multipliers, combinations, and more. Some also allow players to even win free games, similar to winning “free spins” on a traditional video slot. Here’s a quick review of how to play a keno slot: Select the keno slot you want to play (some platforms offer several options) Make your spot selections on various numbers. Some platforms also offer a “quick pick” feature that picks random numbers for you. Hit the “play” button to activate the on-screen hopper and watch the ping-pong balls fall into place to reveal the numbers. Your winnings will be added to your bank based on the number of spots that are connected with the numbers produced by the hopper. Press the “play” button to play again. You can use the same spots again or select new numbers. 2 – Odds and Payouts in Keno Slots When it comes to playing keno, whether the classic live version or on a keno slot game, a player’s winnings are based on the pay table, which includes the number of sports selected and the number of those spots that match the numbers that are drawn from the hopper. The casino generally has a high house edge – usually around 25-40%. Those are some long odds to overcome, but people enjoy the slow pace of the game and fairly modest wagering limits to keep playing. Here’s a look at some typical payouts below (courtesy of chipy.com) for someone who makes fewer picks and catches them all. Please note that some keno slot games pay out set amounts while others pay out varying odds depending on the number of catches. The more catches a player connects, the more a player can win. SPOTS CATCHES PAYOUTS 2 2 15 to 1 3 3 45 to 1 4 4 100 to 1 Here’s another example of spots selected but with fewer catches. Notice the reduced payouts because of a larger number of picks and fewer catches. SPOTS CATCHES PAYOUT 3 2 2 to 1 4 2 2 to 1 5 2 2 to 1 6 2 1 to 1 7 4 3 to 1 So is there a strategy to keno slots and keno in general? Not really as keno is completely a game of chance. Patience is mostly what helps players as they wait and see if their selections appear. Players can’t overcome the house edge in the long run, but keno is usually a fairly easy and inexpensive game to play when betting just a few numbers.[1] [2] [3] “Most players believe that choosing four to eight numbers is the best keno strategy,” Casino.org notes. “This range can give attractive payout odds and feels less risky than selecting one number alone. The more numbers you pick, the higher your chance of matching a winner is. But just remember, the payout multiplier will decrease as your amount of numbers increases.” 3 – Keno Slot Machine Variants Some keno slots and online keno games ramp up the traditional game to make them a bit more like video slots. Some games feature particular themes, such as Buffalo Keno, with game play tailored toward that theme. Pizza Keno sees a couple of pies readied for the over as players connect winning spots. There are other similar games that enhance keno and look more like traditional slots. Other games feature differing elements to enhance the game beyond what one might find on the casino floor. Here are just a few of those added elements: Bonus balls – These can pay out more if you catch these number. Multipliers – Land these balls to see your winnings multiplied. Free games – These can be awarded based on winnings or even at random on some keno slot games. Bonus wheels – This is a popular feature on slots and some keno games even offer the chance to spin a bonus wheel. Autoplay – The game continues to play for several games without having to select more numbers or to hit the “play” button. Winnings are sent to the player bank after each game. Hot & cold numbers – Many online keno slots keep track of numbers that have hit frequently and those that haven’t hit. With fun graphics, sound effects, themes, and game play, keno slot developers have really used some creativity in enhancing what is a pretty basic game. Pick a few spots and give the game a shot!

This classic may be one of the casino’s oldest games historically. “Keno is of Chinese origin and of great antiquity, dating back at least 2,000 years,” the Encyclopedia Britannica notes. “The original Chinese name for the game is baige piao or pai-ko p’iao, meaning ‘white pigeon ticket,’ a reference to the tickets used in a betting game involving homing pigeons.” The game could be found in gambling houses in much of China and some of that original version’s details still remain. The original baige piao “featured the first 80 characters in Qianziwen (“Book of a Thousand Characters”) instead of numbers.” The game is also the inspiration for other similar games like bingo and lotteries. Chinese immigrants brought the games to the U.S. in the 1840s and by the early 20th Century, the game had gained popularity. Casinos and gambling houses originally used the term “Chinese lottery,” converting the symbols to numbers. The game had spread to both Reno and Las Vegas by the 1930s through the 1950s. As slots, video, and computer technology became more prevalent in casinos, seeing more standalone slot-like versions of the game was only natural. As slots became more advanced, translating traditional keno to a slot machine form became fairly common. Players can now find these machines in many casinos and also at online casino platforms, to play for free or real money. The game plays out much like the classic game, but these options also allow for more additional features as well. While keno and keno slot machines can be found pretty easily in most casinos, they are not as popular as other slots and table games. The games can offer some low-cost betting with some fun anticipation mixed in and hopefully a few winning numbers along the way.[4] [5] 5 – Online Keno Slot Machines Finding keno slots online is pretty easy. There are numerous apps available that allow players to check out how the game works and to play for free. Gameplay is very similar to what one might find in a real casino, although there are usually more features and options when playing online. Players looking to wager some real money may also be able to play for even lower limits via an online platform. Playing for virtual coins on a social gaming platform can also be a lot of fun when learning how to play. Seeing some of your “spots” hit the board can still be quite a thrill. Take a quick trip to the App Store or Google Play store and you’ll find popular options like Vegas Keno: Lottery Draw, Cleopatra Keno, Keno Bonus Play, and numerous others. Here’s a look at some of the differences between live and online keno. Live Keno Online Keno Stakes May be small. May be even smaller than found in casinos. Free-to-play options are also available. Speed Can be fairly slow. May move at a quicker pace than the live version of the original game. Gaming options May be more limited. Some platforms offer several options and features. Locations Usually in a traditional casino. Can be found online, via mobile apps, in real-money gaming platforms, and in social gaming environments. 6 – Responsible Gaming When Playing Keno Slots As with any form of gambling, playing responsibly is of utmost importance. Play within your means and only gamble money that you can afford to do without. Any funds for keno slot play should be considered for entertainment only. Don’t tap into money that you would need for day-to-day living expenses. Keno may be a slower game, but wagering large amounts can still really sap your funds. Here are a few tips to remember: Set limits for yourself and stick to them. Take some breaks, especially during losing streaks. Go slowly to make your bankroll last longer. Don’t pick too many numbers. Picking a more moderate collection of spots gives you a chance to win more if your numbers do hit. Play online keno slots for free. This can be a fun way to kill some time and still get some enjoyment out of the game.

Many games feature fun themes and slot players looking for something different may want to give these games a shot. Playing keno slots via an app or online for free is a great way to learn the game and have some fun. Pick those lucky numbers and see how things turn out. Some winnings might just be heading your way.

If you’ve arrived at this page, chances are you’ve played some slots and could be frustrated that you’re not getting the winnings you were hoping for. You’ll see winnings like those of Megabucks at Excalibur in Las Vegas for nearly $40 million, wondering how you can figure out if that’s possible. Here, we’ll aim to learn more about that concept and provide a detailed guide to help you determine volatility before investing.  Understanding Slot Volatility When you walk up to a slot machine in person or load one up online, each has varying degrees of volatility. To put it plainly, some may pay out more often but have more capped winnings, whereas some may not pay out as often but can offer massive winnings.  Slot volatility consists of three levels that distinguish the slots. These include Low, Medium, and High. Low offers more consistent but less high payouts, whereas High offers fewer payouts but potentially massive wins.  Learning about this could shift your entire viewpoint on playing specific slots.  Why Volatility Matters Volatility matters to the casino, retail or online, and the player.  From the player’s perspective, learning about volatility can allow you to gauge what games you do and don’t want to play. That also goes hand-in-hand with managing your bankroll, as the higher volatility games may eat more of it in hopes of a big win.  On the flip side, knowing a slot has higher volatility could allow for more additional entertainment. As you know, these games offer giant potential payouts.  Casinos, whether online or in-person, must know how many of each type to have so that players don’t gravitate more toward one than the other. That said, casinos also need to accommodate players' preferences for what they want to play.  Finally, it also matters in the revenue department, as the more volatile slots could lead to more short-term profits, but if a few big wins occur, they could also lead to losses.  The Risk-Reward Correlation of Volatility As with any casino game, you have to measure the risk and reward aspect of it. Again, in the simplest terms: Higher volatility means fewer payouts, but potential for a big one, whereas low volatility may offer more consistent yet lower payouts, and the big payouts don’t often occur.  You need to gauge this for yourself and your preferred play style. As always, ensure that it’s within your bankroll budget.  Take your pick and enjoy our incredible slots below: Click here to dive into our wide array of free slots. Types of Slot Volatility  When looking into play slots, there are three types of volatility to be aware of: Low, Medium, and High.  Low Volatility: This mode offers more frequent yet lower payouts. The overall gameplay experience is a bit more predictable. It is a great mode for more casual, newer, or risk-averse players.  Medium Volatility: Payouts are not as frequent as in “Low,” but they are more frequent than in “High.” The wins here are more balanced, offering something between massive and lesser ones. This appeals to a more broad range of players. High Volatility: This is for the big-money payouts. However, there’s ample risk as the payouts aren’t as frequent. We’d recommend these games for players with more experience managing their bankrolls and those with larger bankrolls.  Understanding the Difference of Volatility vs. RTP In addition to volatility, slot players should consider RTP, also known as Return to Player Percentage. Below, we’ll examine the differences in these two and how they correlate to one another.  What is RTP?  Return to Player Percentage (RTP) is a metric used to determine how much money is paid back to players over time in addition to the house edge. For example, if a game has an RTP of 96%, this means that, over time, for every $100 wager on the game, $96 is paid back to players.  So, RTP is different from volatility in that it encompasses a more long-term approach to playing the game, while volatility is used to determine the round-by-round play of the game.  The intersection of RTP and Volatility When deciding which slot games to play, you can still use RTP and volatility to determine what to expect from a game.  For example, if a game has an RTP of 98% and is low volatility, you know that low volatility means more frequent wins. The 98% RTP rate further supports that, paying out $98 on every $100 wagered, on average.  Conversely, if you have a game with high RTP and high volatility, the RTP is high, but it illustrates that you might get some high return over the long haul. Again, the wins will be less frequent.  Interpreting RTP and Volatility After learning about both metrics above, you should examine the volatility, especially if you don’t plan on playing one game for an extended period. However, if you plan on playing one slot repeatedly, the RTP will come in handy as it illustrates how much money is paid back to you.  As always, it’s essential to manage your bankroll responsibly.  Methods to Determine Slot Machine Volatility  Whether you’re in an online or retail setting, determining a slot's volatility is essential. Hence, you know exactly what you’re getting into. Online slots list the volatility of the game, and the online casino clearly illustrates RTP and volatility.  However, this isn’t as clear in a retail setting. To examine this, you’ll want to analyze the pay table, observe your play or others', and pay attention to the jackpot and other slot game mechanics.  Pay Table: When you look at the pay table, look for the payout structure involving the rare symbols. This is a great sign that you could be playing a high-volatility slot. Also, see if there are free spins or multipliers. These mechanics are often introduced to high-volatility slots.  Observation: Whether you want to use a portion of your bankroll or watch others, you’ll get a general feel of how often a game is paying out.  Jackpots: If you look at a slot and see the jackpot continuously rising, you’re dealing with a progressive jackpot, which is, more often than not, considered high volatility.  Overall, this information is available if you're online. If you’re in a retail setting, watch other players, examine the pay table, and check the jackpot amount.  Determining the Volatility of Slot Machines in Las Vegas If you’re in Las Vegas and looking to determine the volatility of a slot, follow our tips above for retail casinos. These include checking out the pay table on the slot you’re interested in, playing, and observing how often you win and how often others win. If the jackpot continues to climb, you’re dealing with a progressive jackpot slot that will be a high-volatility game. These retail casino tips apply to all in-person slots in Las Vegas or anywhere else.  That said, if you’re in Vegas right now and need some additional tips, consider these:  Ask an on-site attendant to go through the screens on the slot with you. After that, write down the information you saw to reference it later. This is especially helpful if you’re a new player who may not know exactly what you’re looking at at first glance.  You can also tell the worker that you want to turn off the speed stop to play faster than normal. This will encourage them to assist you more as you’ll likely spend more money since you want to play faster. Another tip is to tell them you’re in town for a short time and want to hit a specific tier amount or that you thought you put in $100 as opposed to $50. When you tell them that, they’ll sort through the screen to see your play history.  Here’s another fun fact about new slot machines: If you’re at the casino and they’re about to install something new, a lot of times you’ll find a paper taped-to machine that may list information about the slot including RTP and volatility. It’s not always the case but again, this is another way to ensure you’re prepared to begin playing.  For more tips, check out this YouTube video from VegasLowRoller, which shows how to pick which slots to play in real-time.  The Mathematic Approach While we’re the furthest thing from mathematicians, there are some ways to approach analyzing the volatility of a slot using math. These include the following:  Probability: This is something used often in a casino setting. When developing a game, a game developer will analyze their bonus features and payout structures to determine the frequency and size of their payouts.  Monte Carlo Simulations: This is another system a developer can use. With this system, you’ll run numerous simulations while accounting for the payout table, features, and probabilities to calculate, on average, what payouts may be.  Check out the Stats: After a game is up and running, a developer can look back at it and see historical trends of wins to determine how often it pays out, including the average win size and more.  Game Design and Slot Themes The overall design of a game and the theme can play significant roles in how volatility is calculated and/or perceived by players.  Above, we discussed how symbols and other features like bonus spins and multipliers can impact it, but offering up a progressive jackpot will also give you a chance to win almost infinite money, so long as it keeps going. A mechanic like this is a great selling point and makes payouts less frequent.  The theme of the game can also play a role. For example, if you’re a fan of a sports team or TV show and your favorite retail or online casino has a game using that license, it could make it higher volatility as you’ll be more inclined to play a game with that theme since it’s familiar to you.  Strategies for Playing Different Volatility Slots While slots are all the same concept—spin the wheel and hope for a win—we’ve learned the importance of identifying volatility. With that, some tips and strategies to deploy in each type exist.  Low to High Volatility Advice Low Volatility: This is a great time to relax. The wins are more frequent but not as massive. For this type of slot, you can come with a smaller bankroll and enjoy yourself.  Medium Volatility: When playing a slot with medium volatility, you’ll have to be prepared to pivot your wager amount based on your overall bankroll. We recommend fluctuating your wagers here a bit to get a chance at bigger payouts but also staying smaller to ensure you don’t run out of cash too quickly.  High Volatility: When approaching a high volatility slot, be prepared with a large bankroll and be equipped with a lot of patience. The wins can be big here, but they may not happen as often. Be prepared to make the maximum wager per round to win progressive jackpots. Otherwise, keep the wagers smaller, but be prepared to wait for a win.  Bankroll Management As with any casino game style, we recommend going into play all types of slots with a budget and staying true to yourself to stick to that number. You should never chase your losses under any circumstance.  As you climb the volatility ladder, be sure that you’re going into each with a slightly larger bankroll than the one before it.  With low volatility, you can have a smaller budget and divide it up over numerous sessions. With high volatility, have a large bankroll to sustain the losses you’ll likely face.  This also goes back to responsible gaming, too. Putting yourself in a position to play strictly for entertainment and not chasing losses is something we adamantly recommend to all prospective slot players.  The Role of Bonus Features in Slot Volatility  You may encounter numerous features when playing a slot, and each can impact volatility differently.  Slot Features Role in Volatility  Free Spins: If free spins are available in a game, players can win without wagering any additional money. However, if there are other features, this could lead to higher volatility. It may not be as volatile if a slot only offers free spins.  Multipliers: Multipliers allow for winnings to be, well, multiplied. These are available in all types of slots, but again, the volatility depends on the overall payout structure.  Wild Symbols: When playing slots, a wild symbol can replace any other symbol and create winning combinations. They can also help be the final piece of a winning payline regardless of the slot's volatility.  How Slot Features Impact Player Experience Whenever a lot has features, this creates additional excitement. Sure, you could have a game where you pull the lever, hoping for a winning payline, and move on, but the features mentioned above provide more variability to each spin, making each much more riveting.  Free spins are like house money. If you get these and win, it’s icing on the cake. The multiplier can make a standard win into something more massive. Finally, Wild Symbols can be, as mentioned, that exciting final piece to cap off a massive payline victory.  Ultimately, these add to the overall entertainment of a game.  Advanced Insights: Volatility in Progressive Jackpots and Online Slots We’ve mentioned progressive jackpot slots a couple of times now, which players will chase, as the payouts can be astronomical.  But how do these and volatility play together?  Examining Progressive Jackpot Slots Whenever you play a progressive jackpot slot, you should already be prepared for a high-volatility game. The jackpot continues to climb as a portion of players' losses are added to the overall progressive jackpot.  Additionally, for most progressive jackpots, you must wager the maximum amount to ensure the grand prize.  There’s a lot of risk here as it’s high volatility, but if you have the bankroll to withstand the round-by-round wagers and for a longer period, go for it.  Online Slots vs. Traditional Slots We also discussed this above, but volatility and RTP information are far more available in an online setting than in a traditional slot.  In a traditional setting, you may find more simplified design slots and something more intricate online.  Since online slots don’t take up actual space on a casino floor, the number of games is much higher, offering plenty of slots with low, medium, and high volatility.  How to Determine the Volatility of a Slot Machine Conclusion Before we leave you here, remember to be aware of a game's volatility if you want to play with any level of strategy. Slots are inherently random, but the randomness is only amplified as the volatility increases.  Understanding volatility is vital to managing your bankroll and managing your expectations.  So, when you head to a casino in person or play online, be sure to remember this page and open it again so you can maximize your bankroll to the best of your ability.  Let’s get out there and win money on our favorite slot games.
