Mr Monkey

Mr Monkey is a brand new slot from GameOS, which was launched this September. The slot itself contains a tropical jungle theme, and has been drawn to offer a simplistic, fun, and a colourful gaming experience. Given the design, the childish graphics, and the simplicity of this slot, Mr Monkey is not a slot to be taken seriously.

The whole premise of this slot is about kind-hearted, good-natured fun. Mr Monkey is typical of a GamesOS video slot in virtually every way, so there should be no surprises with what you find upon the 5 reels and 50 paylines of this slot.

On the plus side, this slot is HTML5 friendly, meaning that it should run on all of your favourite smartphones and tablet devices, too.


GameOS is licensed by the Alderney Gambling Control Commission, and they are not exactly one of the big boys in the casino software industry. Even so, they are still capable of offering you some exciting games.

Their games are commonly found as a supplement to larger developers’ collections at the top online casinos, and many of their slots are as friendly as you what you can find in the Mr. Monkey slot machine. Don’t expect a ton of special features in their games, but payouts do tend to be somewhat reliable and reasonable.

How to play

GameOS have never been one to blend in their wagering control bars very thoroughly. As you can see with the Mr Monkey slot, they have tried to blend in the spin button, by disguising it (rather poorly) as a log, whilst the other buttons take on a jungle green look, but nothing more.

GamesOS has thrown in more paylines than we typically find from them in this slot, but they are still limiting you by forcing you to play with all of the paylines in the game. Minimum wagers will therefore cost you at least $0.50 per spin, whilst maximum stakes are capped at $100 per spin on this slot machine.


Wild symbol: Rather predictably, the Monkey is the wild symbol in this slot. When he appears on the reels of the game, he will substitute for all other icons in the slot, with the exception of other bonus icons.

Wild symbols can also double the value of all winning combinations in which they appear, but they are only capable of cropping up on the second, third, and fourth reels of the Mr Monkey slot.

Scatter symbol: The scatter icon in this game can actually offer you wins worth as much as 400 coins if you can land them in any positions on the reels. Scatters are also the key to triggering a free spins bonus in the game. Land 3 or more symbols on the screen and you will be able to do that.

Super Stacked Free Games: The Super Stacked Free Games feature is the default free spins bonus in this slot. When this bonus begins, the banana symbol will appear stacked on the reels, and any winnings which contain it will be tripled. Additional free spins can also be won during this bonus round, simply by landing more scatters on the reels of the slot.

Maximum pay-outs

The banana symbol is the best paying icon on the game. It will cough up for just 2 symbols appearing in a winning combination. All other symbols require you to have at least a three-of-a-kind to bag a win. The non-progressive jackpot in this slot is fixed at 1,000 coins in total.


GamesOS have developed something of a “doozy” with this video slot. It has good payouts, it has plenty of paylines, and it won’t cost you a packet to play. The extensive set of special features in this game is somewhat rich for a GamesOS slot, and that could be the reason behind its early success.

Mr Monkey is now available to play, and as we’ve mentioned earlier, it is fairly widespread, even though GamesOS are certainly not the largest developers of online slot machine games. Don’t misunderstand, though. We’re not saying that Mr Monkey is going to blow you away, or that it will be the best slot of the year.

We’re simply saying that if you do come across it, it might be worth chucking a few dollars into for a giggle. There are far worse slots out there than this one.
