This jungle-themed Mad Mad Monkey slot from NextGen is a colorful swing through the trees and an encounter with parrots and snakes featuring some of the monkey’s favorite things to eat — coconuts, monkeynuts, and of course, bananas. It’s not a complicated game — definitely good for novice players of online slots as they familiarize themselves with the workings of wilds, scatters, free spins, and all the other classic features of slots. That’s not to say it doesn’t also deliver for more experienced gamers looking for exciting ways to win.

Game Overview

Mad Mad Monkey has a 5-reel setup with 50 paylines and a return to player (RTP) rate of 95.41%. Interestingly, RTPs are often higher in online games than when playing in land-based casinos, which is just one of the many advantages of playing slots online.

This game can be played on any device without losing any of the functionality of its Super Stack, Gamble, and free spins features. There’s also an autospin option for up to 100 spins without having to repeatedly hit the “Spin” button ‒ definitely the ultimate in armchair casino games online. The game doesn’t have a progressive jackpot, but there are plenty of multipliers and a very flexible bet range that makes it well-suited for all risk profiles and pockets.

How To Play

A standard left-to-right combination of matching symbols constitutes a win, with the monkey nuts valued at 300x and the parrot, snake, and banana each valued at 1000x.

The mad, mad monkey of the game’s title is this monkey slot game’s wild, and if he lands on reels 2, 3, or 4, the symbol stacks, and players can double their wins.

The game’s logo is the scatter symbol. Three or more scatters landing anywhere on the reels activate the Super Stack free games feature — during which any wins could be tripled — giving you 10 free spins. There are many ways for players to maximize their free spins, giving you more chances to win with no additional outlay in wagers.


Mad Mad Monkey’s reels are framed by a leafy green surrounding that changes to a light, bright background during the free games when fluttering butterflies and colorful flowers deck the reels. The symbols are all depicted in cartoon style. The monkey is especially humorous, grinning from ear to ear and scampering up and down the frame of the reels from time to time. The low-valued card symbols are entwined with creeping jungle vines. With each spin, a xylophone jingle plays, and jungle beats mark a win and a payout. While not complex in its look and feel, this is a fun game with no pretensions.


The mad, mad monkey himself is the wild in this game and stacks on reels 2, 3, and 4.

The scatter symbol is the game’s logo, and when two or more scatters appear anywhere on the reels, they’ll trigger the free game’s bonus rounds, during which the banana symbol also stacks.

In the Gamble feature, players can gamble any win using the “Gamble” button. If players correctly guess the color of the winning card, they can double their money, but if they also guess the suit, the win is quadrupled. The number of correct guesses is capped at five. But this is not called the Gamble feature for nothing. If players guess incorrectly, they lose everything and are returned to the base game.

The game’s Super Stack feature awards players with 10 free spins and has the potential to pay out triple winnings for a matching combination. During free spins, extra stacked symbols are added to the reels, and there are multipliers on all payouts.

Bonuses and Jackpots

There is no progressive jackpot in Mad Mad Monkey, and the highest payout is 1,000x for five bananas on any one of the 50 paylines. As in all online casino games, the objective is to give yourself the best chance of winning, and in this game, the recommendation is to keep all 50 paylines active during play.

With features that double, triple, and even quadruple winnings, this game has plenty of bonus opportunities that make it captivating for all levels of players.
