Appearance and Sound Effects

As the sound of jungle drumbeats signifies your arrival in the Amazonian rainforest, the star of Mad Mad Monkey cheekily pops his head onto the screen as you spin the reels. The game uses a green banana-filled background, and the reels are surrounded by a wooden pole with vines climbing up it.

The symbols that you can use to create, wins are nature-themed too, and they include multi-coloured parrots, snakes, coconuts, the monkey, the game logo, and two of the monkey's favourite snacks – peanuts and bananas. There are also five low-value playing card symbols which are covered in leaves.

Bonuses and Special Features

The grinning monkey is the wild symbol in the Mad Mad Monkey online slot, which means that he can help you win prizes by replacing all symbols except scatters. The wild appears stacked on the second, third, and fourth reels to boost your chances of creating winning combos.

The Mad Mad Monkey logo is the scatter symbol, and regardless of where it lands on the reels, three or more trigger the Super Stack Free Games Feature. The feature gives you ten free spins, and the chance to grab more valuable prizes with the addition of stacked banana symbols. Any wins that you create are tripled in value. You can win more free games by landing three or more scatter symbols.


Mad Mad Monkey uses five reels, four rows of symbols, and fifty non-fixed paylines, and has an average RTP (Return to Player Rate) of 95.400%. The game lets you create winning combos using matching symbols in succession from the leftmost reel to the rightmost reel.

Mobile Compatibility

The game is designed to work with desktops, laptops, mobile phones, and tablets, and includes mobile-optimised game controls when played on mobile devices.

Our Verdict

Mad Mad Monkey is an amusing, effortless, and fun slot to play, and the stacked wilds and win multipliers can help you become king of the jungle. In particular, the free spins feature with its stacked bananas and tripled prizes can significantly boost the number of credits won.
