Mad Mad Monkey Slot Review

Mad Mad Monkey is a NextGen Gaming slot with a fun monkey theme. This 5 reel 50 payline slot game features stacked symbols to increase your chances of winning bigger. The top jackpot is achieved by getting 5 Bananas which can award you up to £90,000 depending on your stake – you can play from just 50p to as much as £10 a spin.

Look out for the Monkey symbol as this acts like the wild and multiplier – when you get this symbol on any of the 3 middle reels, it will act like a 2x multiplier doubling your win amounts. There are also Monkey wild stacks appearing which can really boost your wins – the good thing is that it also applies in the free spins feature.

This is known as the Super Stack Free Games feature and can be activated when you get 3 or more Mad Mad Monkey logo symbols anywhere in view. You will begin with 10 free spins and 3x multiplier (all wins multiplied by 3 basically) but can gain an extra 10 free spins if you get 3 logo symbols during the feature (giving you 20 free spins in total).

Talking about the Monkey symbol which is the wild/multiplier, if it forms part of a winning combination in a free spin, the symbol will reward you with a 6x multiplier. You can also get stacks which will dramatically increase your winnings in the feature. The Banana symbol can also appear stacked for even bigger wins!

Mad Mad Monkey gives out plenty of smaller wins in the base game but the bigger amounts should be won in the free spins feature. If you get the Monkey symbol forming part of a few free spins wins, the 6x multiplier can really boost your winnings to a new level. I much prefer other NextGen Gaming slots like 300 Shields which is quite a bit higher variance. Saying that, if you like crazy monkeys, Net Entertainment’s Go Bananas is a better game and has 5 monkey wild symbols.
