For many slot players, the ultimate dream is to hit a jackpot. Whether you're playing in a casino, online, or with friends in a social gaming setting, the idea of winning big is a common goal. Jackpots come in different sizes – mini, major, or minor – and they can turn a regular slot session into a winning one. While those massive six- and seven-figure jackpots are alluring, the odds of winning them are quite long, including one in 34 million for games when you wager the maximum amount. The odds could be even higher or lower, depending on the game.

But it's not all about the huge jackpots; smaller jackpots happen more often with better odds. So, what are the actual chances of hitting a slot machine jackpot? This article explores those odds, the factors that influence them, and whether any strategies can increase your chances of winning.

What’s a Jackpot in Slots?

Those new to slots may not realize exactly what a jackpot is. A jackpot is generally considered a much larger payout than one might find on a normal spin of the reels.

The pay lines on a modern slot machine offer numerous ways a player can theoretically win. However, not all of those are considered jackpots. These larger payouts are much rarer and may even require what is called a “hand pay” at a live casino. This means that a member of the casino staff has to pay out a player personally “by hand” because the jackpot is so high. That may also require a winner to fill out a tax form, although that may not be a major concern considering you’ve just hit it big.

These jackpots mean that a player will usually see multiple symbols that occur less frequently on a single spin. A player faces much longer odds in seeing events like this happen. Sometimes these wins may also come in bonus games or free spins.

These are extra winning opportunities a player receives by seeing certain symbols in the game to trigger these bonus opportunities. The chances of winning larger prizes may be better in these bonus games, but not necessarily for those much larger jackpots.

Types of Jackpots

Players hoping for a big jackpot always have a shot at a larger payout at least to some degree. But it’s important to remember that a casino has a house edge when it comes to slot machines. There is no legal way to overcome this such as card counting in blackjack or gaining a skill edge at the poker tables.

Luck is a key factor in playing a slot machine, especially in winning one of those massive jackpots that make headlines. However, jackpots of various types are available for those who take a seat at a slot machine or play online.

According to SciPlay director of slot strategy and performance Kelly Trask, being aware of the various jackpots and your possibilities of winning can help a player form reasonable expectations:

When you walk into a casino it’s easy to be distracted by the bright lights, the music and all of the energy behind the bells and whistles of slot machines firing off bonuses and jackpots! Your odds of hitting a jackpot vary greatly on which machine you’re playing and how the RTP to those jackpots are being distributed. Some casinos also have linked jackpots where the Grand Jackpot is shared across multiple machines, every spin on any of those linked machines has a faster chance of being the winning spin!

Here’s a look at a few jackpot types.

  1. Mini Jackpot – These are smaller jackpots one might find playing a typical slot machine in a casino. These usually come about by triggering certain bonuses or finding a certain number of key symbols on the reels. These may include multipliers that increase a player’s winnings. Mini jackpots are much more common than larger payouts. Obviously the higher the jackpot, the longer the odds are of hitting it. This is the first tier usually on a slot machine’s jackpot sequence.

  2. Major Jackpot – This is a larger jackpot than the Mini version and the second tier of larger payouts on slot games. As expected, players face larger odds of achieving this level. While on a penny machine, a Mini Jackpot may be $50 to $100, and a Major may bring a few hundred dollars.

  3. Minor Jackpot – This is the third tier of the jackpot and sees that potential payout rises even more. This is a more difficult level to reach because of the longer odds involved. This type of jackpot could register a few thousand dollars for a lucky player. This may not be life-changing money, but any player would be happy to see the bells and whistles on a machine go off to advertise this type of win.

  4. Mega Jackpot – This is a hefty payout as the name implies. A player hitting a Mega Jackpot has accomplished something and can usually expect a payout of up to tens of thousands of dollars at least heading their way. These can be huge payouts and don’t come around every day for slot players. They are more difficult to achieve with longer odds.

  5. Progressive Jackpot – These are colossal seven-figure and higher jackpots that might even make headlines in the new media. A progressive slot is tied into other machines throughout a certain state or territory. With so many machines feeding money into the prize pool, these potential payouts can get truly astronomical. The odds of winning these types of jackpots can be astronomical as well. For an in-depth guide on mastering slot machine gameplay, click here.

Some jackpots may also vary or have slightly different names than those above, but this is the general sequence and names for slot machine jackpots. Some players may also see payouts called Local Jackpots, which are similar to progressives but may include players in a pool smaller than a traditional progressive but still achieving larger jackpots than traditional games. Huge jackpots in these games can also be rare as well.

Odds of Winning a Jackpot

As noted above, hitting those massive jackpot payouts isn't easy. The reason those huge paydays make news is because they’re not only handing a player massive money, but they’re also extremely rare considering the number of players pumping credits into slot machines around the world each day.

The largest jackpot in history came in 2003 at the Excalibur casino in Las Vegas. A software engineer played about $100 in a Megabucks, a popular progressive machine seen at casinos around the world. When three Megabucks symbols stacked up on the screen, this player struck gold – taking home $39.7 million.

So what are the odds of actually winning a million-dollar jackpot, not even one at these gargantuan levels as won at the Excalibur? Numerous intricacies in each game can make this vary, but in general, many experts concede that the odds of hitting that kind of jackpot come in the range of 34 million to one or even as high as 100 million to one.

Just as a comparison, the odds of getting struck by lightning are about one in a million, according to the U.S. Centers for Disease Control. That shows just how difficult it is to win one of these life-changing prizes.

Also, playing progressives to win at this level usually requires betting at the max-bet level and higher stakes. This allows a player to win, but those odds at huge payouts are still long.

Here are a few pros and cons of playing progressive slots:


  • Chances at larger payouts

  • Usually, better comps/rewards because of higher limits

  • Better chances at smaller wins because of higher RTP


  • Can deplete a bankroll at higher betting stakes

  • RTP may not be that much better depending on individual games

  • May have more limited game options, depending on the casino or online site

  • Does that mean a player shouldn’t hop in a casino for some fun or fire up the computer or mobile device for some online slots? Certainly not. Slots should be seen as a form of entertainment only with a chance that you could win some money on a gambling excursion.

  • Players regularly win smaller jackpots and these are much more likely than a massive progressive jackpot. A few nice scores and a winning session can make for a fun night spinning those slot machine reels.

Improve Your Chances to Win Slot Jackpots

Winning jackpots on slot machines primarily relies on chance, and there's no foolproof strategy for guaranteed success. However, you can maximize your odds by choosing high RTP machines, betting responsibly, understanding the game mechanics, considering progressive jackpots, and practicing responsible gambling. While some believe in optimal timing, the key is to enjoy the gaming experience while keeping in mind that it's fundamentally a game of luck.

Jackpots: Online Versus Live Casinos

As noted, the odds of hitting massive jackpots are long. Online slot players face similar odds, but there are some opportunities to win major payouts at a virtual casino as well. Players playing online casinos or on social media platforms, such as at Jackpot Party, can expect some opportunities to see some major boosts to their credits if those reels line up just right.

Do slots pay out better than live casinos when it comes to slot games? Probably not. Your chances of winning largely depend on the RTP of each game, whether in a casino or an online setting.

Numerous online sources offer the RTP of individual casinos, whether in Las Vegas, Atlantic City, London, Monte Carlo, or some other location around the world. Many RTP rates are also available for online casinos.

An RTP rate can also vary by game, and that can often be found online as well. A game or casino with a 96% RTP has a better shot at winning than a game or property with a 92% RTP.

Players having some fun playing in a social gaming environment are usually playing simply for virtual coins and player rewards within the game. These types of games usually pay out more regularly than a real casino. The operator hopes to keep players at the games and there isn't any money involved.

Exploring the differences between playing online and live casino slots goes beyond odds and RTP rates to the overall experience. Online casinos offer the availability to play at any time and a large game selection, while brick-and-mortar casinos offer a unique, immersive environment with real social interaction. Each has its benefits and drawbacks, and it all depends on your personal preference. Knowing both the statistical and the social sides of gaming can greatly influence your gaming experience, whether you prefer the convenience of playing online or the lively atmosphere of a casino.

Frequently Asked Questions

Do I have a chance at winning a huge slot machine jackpot?

More than likely not because these levels of payouts are so rare and players face extremely long odds. You do have more opportunities at smaller jackpots, however, which can also come with nice payouts.

What are the odds of winning a progressive jackpot?

The odds of winning a seven-figure jackpot may be as high as 50 million or 100 million to one. However, smaller jackpots can come with much lower odds and regularly reward players with some big payouts both in live and online casinos.

What’s a way to reduce the odds against a player winning?

Play games with higher RTP (return to player). This is the percentage of money in a slot that a casino pays out to players. The higher the RTP, the more likely a player has a chance at a winning session.

How to Hit a Jackpot on a Slot Machine?

While there's no guaranteed way to hit a jackpot on a slot machine, you can improve your chances by understanding the game's mechanics, betting the maximum amount if possible, and choosing the right machine with a high RTP (Return to Player) percentage. Progressive jackpot slots may offer larger prizes, but they often require maximum bets for eligibility. It's crucial to manage your bankroll wisely, practice responsible gambling, and remember that ultimately, hitting a jackpot is a matter of luck.

How Often Do Slot Machines Hit the Jackpot?

The frequency with which slot machines hit jackpots varies widely depending on the specific machine and game. Typically, slot machines are programmed to have lower odds of hitting the jackpot, as these are often life-changing sums. Smaller jackpots tend to hit more frequently, while the massive progressive jackpots have much longer odds and may not hit for extended periods. The exact rate at which jackpots occur can be influenced by factors such as game design and random number generation algorithms, making it difficult to provide a precise frequency.

How to Tell When a Slot Machine Is About to Hit the Jackpot?

Slot machines operate on random number generation algorithms, making it impossible to predict when a jackpot will hit. There are no reliable indicators or signs that can predict when a machine is about to hit the jackpot. Each spin on a slot machine is independent, and previous outcomes do not influence future spins. It's important to approach slot play with the understanding that it's a game of chance, and there are no foolproof methods to predict jackpot wins.

Can You Win a Jackpot with Minimum Bet?

In many slot machines, it is possible to win a jackpot with a minimum bet; however, it's essential to be aware of the specific rules of the game you're playing. Some slots have fixed jackpots that are not affected by the bet size, meaning you can win the jackpot with a minimum bet. Others, particularly those with progressive jackpots, often require players to place maximum bets to be eligible for the top prize. Always check the game's paytable and rules to determine the betting requirements for the jackpot in the slot machine you're playing.
