Monkey Mayhem is a classic slot by Merkur, released in August 2018, and it has a friendly and fun theme but is a high variance slot. Monkey Mayhem doesn't have a free spins game or any bonus features other than the Exploding Wilds. That's the one and only thing to look forward to in Monkey Mayhem.
The game uses nine normal symbols, four of which are low value card symbols. The remaining ones – Coins, Bananas, Coconut, Palm Tree and Tree House all pay roughly the same, which is to say they only pay well when you land five-of-a-kind. Most of the time nothing will be happening on the reels as symbols fail to align on one of 10 fixed paylines, and Monkey Mayhem pays really rarely.
The main and only feature of the game are exploding Wilds, and this doesn't happen frequently either. In theory, it's enough to land a Monkey Barrel on any of the reels, then the Barrel will explode and will award some more Wilds. In practice, this is a rare event, and even when it happens there's a lot of variance to it as Wilds closer to the left are more valuable than the ones on the right – which seem to be more common. In any case, playing Monkey Mayhem needs patience as this is a high variance game that pays rarely. Theoretical return to player (RTP) is 96.03% so player can be sure they aren't getting robbed even after a long period of non-winning spins. It's just that this game is set up to not pay often.
The potential to win is here, however, as the Monkey Barrels can produce a giant win if and when everything aligns perfectly. The best-paying symbol in the game, Tree House, pays a 30x prize for landing five-of-a-kind, and with 10 paylines the maximum possible prize on a single spin is 300x, and the exploding Wilds help greatly with completing those paylines.
Monkey Mayhem uses a classic slot theme, with card symbols and familiar sounds of reels spinning. Despite the graphics which aren't too bad, it's only the Monkeys that add some fun to the theme, and most spins go without a Monkey. The theme is as colorful as you'd expect from a jungle theme with monkeys, and it works well although it's nothing that hasn't been seen before in a plethora of similar slots.
For those willing to play a game that seemingly never pays, and who are prepared to wait for a while to get that big win, can find Merkur Gaming slots in those casinos that made it their business to offer all possible slots. Brands like SlotsMillion or Videoslots, of course, have slots by this slot developer, and some others such as Cashmio or Lapalingo also host Merkur games.
