The biggest and best payout slots you can play online in 2025
Looking for a the biggest possible payout when playing online slots? We’ve collected five slots offer some of the best jackpots you can find when betting online — if you don’t mind taking on a little more risk in exchange.
When looking for slots that have large payouts, there are various metrics to consider. For consistent payouts, one might first pay attention to the slot’s RTP. This stands for “return to player,” referring to the percentage a player wins back of their bet. For example, 95% RTP on a bet of $100 would give players back a maximum of $95. But that’s not necessarily the best indicator of a high-paying slot. You might instead need to look for the max win amount, which indicates how many times the player’s original bet a player can make with a win. For example, 10,000x a $1 bet would be a $10,000 win.
Here are some of the biggest payout slots that consider both of these metrics to offer some of the best experiences in online slot play.
Marching Legions
The intense Marching Legions slot sees bettors taking control of the Roman Empire’s army across its reels. An epic soundtrack adds to the intensity and excitement. But the real standout of Marching Legions is its big win capabilities.
Marching Legion has an RTP up to 98.12%, a 25.62% hit rate, and the chance to win up to 10,000x the stake. It’s a high-volatility game that offers chances for big wins, but can also be quite unpredictable. Of course, that’s part of the fun for many players.
Marching Legions has seven regular symbols, three low pays, and four premiums. There are no wilds, but there are legionnaires who can trigger respins, free spins, and nudges. Nudging means that stacks of legionnaires may move up or down the reel to cover it entirely. During the Free Spins round, which are triggered by landing on three symbols of a certain type, collect stacks to fill a meter.
Blood Suckers Megaways
Bettors who were impressed with Marching Legions’ max win may want to sit down for this — Blood Suckers Megaways features a very high RTP of 97.66% and a crazy maximum win of 20,513x the initial stake bet. This is much higher than what was featured in the original Blood Suckers slot (1,014x) or in the popular Blood Suckers 2 (1,298x). The number of ways to win can be as high as 117,649, one of the signatures of Megaways slots and a sign of a big potential payout.
The more matching symbols players get in Blood Suckers Megaways, the bigger the payout. The Megaways mechanic means players can get a minimum of 2 and a maximum of 7 symbols per spin, meaning more chances to find a winning combination. If all six reels have seven symbols, that’s 117,649 ways to win.
Blood Suckers has a horror theme inspired by hungry vampires roaming Victorian streets hundreds of years ago. The soundtrack is appropriately eerie, making this slot feel quite immersive. The symbols include Nosferatu, Vlad the Impaler, and other known vampires from throughout fictional history.
Tombstone R.I.P.
Tombstone R.I.P. is a very dark slot that might scare away some players — until they hear of the win cap of 300,000x the bet. It takes place in a grim western town with lifeless characters, sharing frightening imagery with players throughout their time with the game.
With Enhanced Bet active, the RTP reaches up to 96.25%, but don’t expect an easy saunter into the sunset. Tombstone R.I.P. was called “insane” by creator Nolimit City due to its incredibly intense volatility. The hit frequency is very low at just 8.7%. There are bonus features like Scatters, Hang ’em High Free Spins, and Boothill Free Spins, the last of which unlocks the 300,000x win cap but at a 1 in 16,000 chance of hitting. It’s safe to say that Tombstone R.I.P. isn’t the most relaxing slot to play, but it does offer huge opportunities to lucky players.
Starburst XXXtreme
A classic slot in style featuring gem-inspired symbols and expected casino visuals, Starburst XXXtreme stands out in other ways — most prominently with its massive win potential. The slot features an RTP of 96.26%, high volatility, and a max win of 200,000x the bet. The max wager is $50, meaning bettors can potentially get a spin worth $10 million.
Starburst wilds are the highlighted feature, replacing other symbols to form winning combinations. They also reward multipliers when hit on the reel, reaching up to 150x the bet. They expand across entire reels and lock into place for a respin. If multiple Starburst wilds show up during a respin, they combine multipliers together. A Random Wilds feature can add up to three Starburst wilds to the reels on just one spin.
The blend of high wins, fun, classic visuals, and a fun soundtrack make Starburst XXXtreme a favorite slot machine for those looking for big payouts.
Money Train 4
For bettors willing to brave a potential brutal experience in the name of truly big rewards, it may be time to buy a ticket to Money Train 4. Explore a futuristic dystopian world that changes depending on what bonuses you unlock in the game. The visuals, graphics, and sound of this slot create an immersive experience reminiscent of a big-budget sci-fi movie. But players won’t just be sitting back and relaxing with a tub of popcorn in their arms.
Money Train is a high-risk, high-reward slot that has a payout up to 150,000x your bet. It’s a highly volatile slot that will leave players on the edge of their seat, hoping to unlock respins, Money Cart bonuses, and more in hopes of not being left behind as the train careens down the track.
Any of these five online slots are capable of triggering a big payout for bettors willing to brave them. And for those who are, that sense of risk is often half the fun.
