Mad Mad Monkey Slot NextGen Gaming

Mad Mad Monkey is 5 reels and 50 pay-lines video slot powered by NextGen Gaming software provider. The theme of this slot is the jungle life with a slightly crazy and odd monkey as the central character. It is pretty colorful and happy theme with symbols such as high card symbols, peanuts, a snake, a banana, a coconut, and a parrot. Give this mad slot a spin here for free or visit any of the NextGen Gaming Casinos to play for real money.

Before you enter this crazy jungle with this eccentric monkey, you need to adjust your bets. First set of "+/-" starting from left to right, are used to set the number of lines. Next to them there is another set of "+/-" buttons which are used to set coins size that ranges from 0.02 to 0.40. "Gamble" activates the gamble feature, and "Autoplay" and it is used to set the reels in motion without interruption for a desired number of times. "Spin" button is used to spin the reels.

This video slot lacks in the special features and symbols department but if you give it a chance it will not disappoint you with its interesting game-play. The symbols involve a Wild, a Scatter, Super Stack free games, and Gamble feature.

The Wild symbol of the game is the monkey himself. It can substitute for any other symbol except the scatter. If this symbol appears on reels 2, 3 and 4 it will become stacked and the wins will be doubled. Mad Money symbol stack can bring you mad prizes.

Mad Mad Monkey game logo is the Scatter of the game. If you land 3 or more of the scatters anywhere on the reels you will activate Super Stack free games feature. Once the free games are activated you will get 10 Free Spins and all potential winning combos you hit will be tripled. If you land another three scatters you will win additional 10 Free Spins. Furthermore, the banana symbol can also become stacked symbol on the reels during this feature.

The Gamble feature can be activated whenever you land a winning combo. It can be done by clicking on the "Gamble" button. Here you stand to double or quadruple your winnings. If you guess the color of the card you will double the winnings, and if you guess the suit your winnings will be quadrupled. If you make a wrong guess you will lose everything and you will be taken back to the base game. You are limited to 5 correct picks.

Whenever you play with a monkey, the monkey would play for you, or it would play you out! That's what is call a monkey business! Hahaha. This Mad Mad Monkey game from NextGen was exactly that for me - playing monkey business all the time, and playing me out each and every time too! Okay, so some players did get lucky with this monkey, but that was some years ago - try playing this game now, and you'd no longer get a monkey that plays for you! You'd most probably get played out, just like it did to me!

First off, I wasn't happy at all with its 5-reels 4-rows format, playing with 50 paylines, and with a minimum starting bet of $0.50 - that's one row too many, and double the cost for each and every spin for me. Yeah, rich players are not bothered by all these, but what about poor and small-fish players like me? I would only play with $0.50 bets per spin on my favourite game, because I know what to expect from the game, but playing with $0.50 bets per spin with a monkey? Sheesh! Okay, thankfully, the paylines can be selected, so there's never a need to keep on playing with 50 paylines - in fact, I only played with about 25 line most of the time! Hahaha.

The Monkey is a stacked Wild symbol on reels 2, 3 and 4, is a non-paying symbol, much to my dislike, but luckily it doubles all wins with it. Otherwise, I'd get a bunch of stone bananas and throw them at this monkey! The logo 'Mad Mad Monkey' is the Scatter symbol, paying a nice 400x total bet for getting 5 of them, which is more like it. Getting 3 or more of these Scatters awards 10 free spins with all wins tripled - not too bad but still not good enough (it should have been the usual 15 free spins with a 3x multiplier). However, the Free Spins game can be retriggered, so that removed that bunch of stone bananas I had kept, waiting to be used on the monkey! Hahaha.

Other than that, nothing else is to my liking. The paytable isn't good, the win values for all the symbols aren't good either, and getting 5 Wilds on a payline would only pay a lousy substituted win of 20x the total bet amount! Get 5-Wilds on all 50 paylines, for a 1000x total bet win? Wait until Doomsday comes, it still cannot happen! Hahaha. The best you can expect out of this monkey would be some decent wins of up to 250x, maybe even up to 500x, but I really wouldn't expect anything more than that.


I've played with this monkey on so many occasions so far, I've been monkeyed around for so long and for so many times already, but not any longer. This monkey may not have gotten my stone bananas, but it certainly got locked away permanently somewhere in an unknown jungle! Hehehe.

Mad Mad Monkey is a game I only tried quite recently. Yes I had tried it in the past but I hadn't had very serious sessions with it so recently I decided to give it a decent try. I know that many players find this game to be a great one so I wanted to see what the hype was all about.

From technical point of view this game is very simplistic and I love it. It has 5 reels and 50 paylines, so the minimum bet costs 0.50$, however you can lower the amount of paylines which is great, if you're working with a smaller balance.
Bonus wise this game has only free spins bonus but that's fine by me as free spins are the bonus feature that usually has the highest win potential for the game.

So the visual inspiration for this game comes from Jungle theme as the main characters are monkeys, which are also wilds, and you'll also see snakes, coconuts and other things that come in association with the jungle. I can't say that this game design is my favorite, but it works good and I wasn't annoyed looking at it even after a longer time.

So I had over 30€ balance when I started to play this game. I really like the fact that this game has wild symbols that can come up staked on middle reels. After spending some time with this game I found them to be very handy. In my session I managed to get a few 40x bet wins on base game thanks to the wild symbols and for a while my balance was steady due to the small yet regular base game wins.

I have had the bonus feature several times now and I do think that it is worth waiting for. For 3 scatters you get 10 free games with 3x multiplier. The symbols can ome up stacked, just like wilds and although my best win on free spins hasn't gone over 100x bet, I feel like there is definitely good potential because of the wilds.

So overall I do think that this is one of the best Nextgen games, I feel like it is simplistic and design isn't really my cup of tea, but I enjoyed the game and I think that the free spins have good winning potential. But I will also have to say that I won't be playing this game with low balance as it can also be quite  a money eater and I did lose around 70€ in less than an hour, playing with minimum stakes. I'd recommend it from what I've experienced.

Mad mad monkey is slot game made by Nextgen. This is interesting game which I played couple of times at guts casino, but not so often because it has high bet per spin, and also could eat money quickly.

I like how this game look, and also I like sounds. Of course everything is far away from perfect, but still very good.

There is 50 paylines in this game, and also apart from regular looking game there is 4 rows and not 3. This is why this game has more lines than usually. Gameplay is very simple, because there is stacked wilds on 3 middle reels. Without stacked wilds it is very hard to get any decent win, if only 5 bananas which is highest paying symbol. Others pay much more lower, but no surprise because there is stacked wilds.

There is also freespins feature, starting when 3 or more scatters appear anywhere on reels. You then get 10 freegames with x 3 multiplier, but also bananas become stacked. In dream hit you will have full screen of banans, and payout will be great. But Stacked bananas appear still very rare.

I never had more than 100 bets during freegames or normal play in this game. But I had a lot of smaller wins, and they come pretty often, because wild monkeys land often. Also there is very good gamble option, it can help you if you want to double winnings. I tried it couple of times and was able to win with it very good couple of times. But also due to high bet size I am not often player in this game.

Also game can be brutal, couple of times i lost about 40 - 50$ on my balance just playing this game, and this is not why I really like.

I rate this game with 8 stars.


High min bet. Freespins feature seems good potential, but it is hard to get stacked bananas during it.
