Hell Mania Review
SYNOT might be a rather unassuming company at first glance, but we can tell you that it has a very long track record of releasing polished mid-range slots that can give you plenty of fun for a quick session or two. In 2017, SYNOT launched a game called Hell Mania, and it’s that release that we’ll take a look at in this review. Its playing field is quite simple, as it has just 5 reels, 3 rows and 5 paylines.
The theme of Hell Mania is rather devilish, and you can look forward to stylish and colorful symbols. The entire game has a fairly cartoony feel, and that won’t be to everyone’s liking, but it’s fair enough and certainly pleasant to look at!

The mathematical model of Hell Mania combines a medium volatility level with a decent 1,024x jackpot, and its hit frequency is 11.42%. Low rollers can try their luck for bets as low as £0.20 per spin, while the game’s max bet stands at £100. As for the theoretical RTP of Hell Mania, it’s always between 88.16% and 98.01%, with the default value clocking in at 96.06%.
Hell Mania Slot Features
There are as many as 11 pay symbols in Hell Mania, and they are split between 5 low pays, 2 mid pays and 4 high pays. For low pays, there are your basic card ranks from Tens to Aces, though they do come with fairly colorful designs. In any case, these symbols are worth up to 8x your bet for a five-of-a-kind combo. For mid pays, there are tridents and chalices, with these symbols paying up to 30x your bet for a full set. Finally, there are hearts, crosses, pentagrams, and even horned devils. These four symbols pay even in sets of just two, and the top win is 500x your bet. To get it, you have to land five horned devils on a payline.
For specials, there are Succubus Wilds that substitute for pay symbols and that work as Expanding Wilds, which means that they can expand to cover entire reels.

Gameplay-wise, there are no respins or free spins in Hell Mania. You can, however, take advantage of Full Reel Multipliers. If you land full reels of matching card rank symbols from left to right, you’ll get a nice win multiplier for your total win. For 3, 4, and 5 full reels, the win multipliers are 3x, 4x, and 5x, respectively.
Players can also try to win more via the Gamble feature, which comes in the form of a small minigame that’s all about trying to guess the color of a face-down playing card. A correct guess will double your win, while a wrong one will take your winnings away.
Review Summary
In short, Hell Mania is yet another solid yet unexciting release from SYNOT. We like its colorful symbols, Expanding Wilds, and Full Reel Multipliers, but it all runs out of steam rather quickly, since there are no free spins or major features to look forward to.
