The banana is the top-paying icon and only needs two to pay out, while otherwise three matching slot symbols are required. The monkey acts as the game’s wild and also doubles any wins to which it contributes.
- All symbols: 12
- Highest-Paying Symbol: Banana
- Wilds: Wilds
- Paylines Pay: Left to Right
- Maximum Win: 6,000x the stake size
Mad Mad Monkey Bonuses & Features
The Wild symbol is a crucial slot feature on Mad Mad Monkey. It has the ability to turn stacked, therefore filling the reels and contributing to more winning lines.
At least three Scatter symbols are needed for players at UK online casinos to get to try out the free spins bonus round on Mad Mad Monkey.
When this triggers, 10 free spins for the bonus round will be awarded and there is a 3x multiplier in play throughout the Mad Mad Monkey mini-game too.
Players will receive another 10 free spins on the Mad Mad Monkey bonus game if three or more Scatter symbols drop, so the bonus can be retriggered.
Due to the Super Stack feature, the Wild and icons featuring bananas can also fill the whole reel, which adds to the monkey madness on the slot.
Mad Mad Monkey might be a little light on slot features compared to some new slots that drop at UK online casinos, but it provides uncomplicated fun.
Similar Games & Best Alternatives
As the original was such a hit, a slots sequel – Mad Mad Monkey II – was released for fans of the game and it remains a popular pick at UK online casinos.
Other ape-themed slots that are highly recommended include the King Kong Cash series, which has spawned a large range of slots sequels due to its popularity. The pick of the games is King Kong Cash Even Bigger Bananas Megaways.
Monkey Madness Proves a Hit
While Mad Mad Monkey does not pack in as many slot features as most new slots that drop at UK online casinos these days, the uncomplicated nature of the base game and bonus round are likely to find fans.
The maximum win of 6,000x the stake size is solid, but 95.40% RTP is not the best although medium volatility is better. One for fans of animal-themed slot games.
