Mental slot

One of the most contradictional NoLimit City video slots is Mental released during the summer of 2021. This creepy horror-themed casino game is too dark even for the most dedicated fans of the genre. The features RTP of 96.06% is nothing special, but players keep winning outstanding rewards.

We’ve recorded 8 stunning wins, including a marvelous $533,328 in August 2022, when the max payout multiplier of 66,666x was reached.

Bonus Rounds And Big Wins In Slots

Most of the big win slots offer a variety of bonus rounds and features, although some classic-themed games stick to simpler gameplay. If you follow the links in the previous section and read how the biggest rewards were won, you'll notice a repeating pattern. Most of them were won during Free Spins or another multiplier-enhanced bonus game.

Moreover, not just the big win casino games, but all of them offer their maximum payouts under particular conditions. First, they are very rare, and sometimes more than 10 million spins are required. But most importantly, they come with the help of a multiplier, and we all know that this feature is mostly active during bonus minigames.

Average RTP In Big Win Casino Games

A common and debated misconception is that you have to play the highest-RTP titles to benefit from slots big win situations. Well, these games deliver better return to player rates in the long run, as we all know that RTPs are theoretical indicators. They are not a guarantee for massive wins or progressive jackpots.

That's why slots with extremely low payout rates, like Mega Moolah, are so popular despite this major drawback. Most of the big win casino games have variable RTP rates, and they are around 95 - 96% in most cases. Then again, this is not a recommendation for novice players, as I made this conclusion after years of experience.

Tips For Playing Slots With Biggest Wins

Strategies for winning big win slots can be hard to come by, as players looking for massive payouts usually rely much more on luck than anyone else. Furthermore, most of the betting schemes and tactics commonly used in online gambling aim to deliver stable income and longer gameplay. Here is my advice that might help you hit the jackpot:

  • Choose big win casino sites with a proven track of paying large prizes
  • Play with bonuses or promotions that will keep you in play longer
  • You should bet big, as high rollers have better chances by rule
  • Test the game you like in demo mode and try its features
  • Use the Bonus Buy if your budget allows it
  • Despite all, prepare a budget and stop playing if you zero it


There are many big win slots out there, and nowadays, most providers release titles with extended betting ranges. Some games pay generously in big periods of time, while others can do it several times per single year. It all depends on your financial capabilities and willingness to risk.

There is no way to predict a properly working RNG slot machine. The big wi casino operators always highlight the fact that their platforms are verified by reputable auditors. That's the first thing to check before bringing your fat wallet into play. The rest is more or less luck, and we wish you as much of it as possible!
