Crazy Monkey is a five-reel, nine-line video slot from Igrosoft, a studio that started in Moscow in 1999 making software and cabinets for slot machines. The Crazy Monkey slot is about as plain as video slots get. You choose how many lines to play, set a bet and spin. Three or more monkeys open a two-stage bonus in which the monkey pulls ropes for prizes, and any regular win can be gambled in a card risk game. No free spins, no multipliers on the reels.
This guide goes through what the paytable says, how the two features work and which numbers are still unknown. When we checked on 11 November 2026, Igrosoft’s own site showed nothing but an “Under Construction” notice. So wherever a figure comes from a game catalogue rather than from the studio, we name the catalogue.
What you see on the Crazy Monkey reels
The Crazy Monkey slot machine screen belongs to the cabinet era. A blue-grey 5×3 grid sits inside a frame of jungle vines, coloured line numbers run down both sides, and TOTAL BET, LINE PLAY and CREDIT counters sit across the top. The monkey waves at you from the bottom edge. Every payline is numbered on the frame, and in the classic layout you activate 1, 3, 5, 7 or 9 of them.
Bets run from 1 to 810 credits per spin in the version SlotCatalog and VegasSlotsOnline list, and the Russian-language game screen prints the same range (“игра от 1 до 810 кредитов”). A few reviews quote a lower ceiling of 225 credits, or 25 per line. The limit you actually get depends on the build your casino runs, so look at the bet panel before the first spin.
Crazy Monkey symbols and what they pay
Wins pay left to right on an active line. The figures are for five of a kind at one credit per line, as listed by SlotCatalog; VegasSlotsOnline gives the same top values. Multiply by your line bet.
| Symbol | Role | Five on a line |
|---|---|---|
| Crazy Monkey logo | Highest regular symbol | 5,000 |
| Tribal mask | Wild: stands in for everything except the monkey | 2,000 |
| Lion | High | 500 |
| Pineapple | Middle | 200 |
| Anvil | Middle | 100 |
| Snake | Low | 50 |
| Banana | Low | 20 |
| Butterfly | Low | 10 |
| Monkey | Starts the bonus game | no line pay listed |
The catalogues can’t agree on a name for the wild. One calls it a tiki mask, another a golden skull. On the reels it is a carved tribal mask, and it pays on its own as well as substituting. The monkey matters more than any of them, though, because it is your way into the bonus.
The rope bonus, in two stages
Land three or more monkeys and the reels give way to a screen with five ropes hanging above the monkey. You choose the rope he pulls. Some ropes hold a prize, others a heavy object, and if an anvil lands on his head the round ends there. Get through all five and you reach stage two: two boxes with question marks, one of them holding a large prize. Pick the wrong box and you still keep everything the ropes paid.
One review says the monkeys can land anywhere on the reels; the others don’t say. The help screen of your casino’s version is the final word. Which rope hides the anvil is decided at random, so there is no rope order to memorise. The how-to-play guide spends its time on bankroll for exactly that reason.
Doubling a win in the risk game
After a regular win you can collect it or press into the risk game. The dealer’s card is turned face up and four cards lie face down. Pick one. Higher than the dealer’s doubles the win, an equal card leaves it unchanged, and a lower card wipes it out. You can keep doubling or take the money at any point.
It is roughly a coin flip with a tie thrown in. One wrong card erases a whole run of doubles, so we would only use it on small wins we are happy to lose.
RTP, volatility and the numbers nobody publishes
We found no RTP for Crazy Monkey from Igrosoft itself. Catalogues list 95% (VegasSlotsOnline) and 96% (SlotCatalog, which also flags that the figure can vary between versions). The honest summary: about 95 to 96 per cent over a very long run. The casino keeps a few credits of every hundred wagered on average, and a single evening can land far from that average in either direction.
SlotCatalog’s review calls the volatility medium. That fits the paytable: most symbols pay modest amounts, and the big money sits with the logos, the masks and the bonus. Maximum win is the murkiest number of all. SlotCatalog’s data field says N/A while its review text mentions 11,750 times the stake, so we don’t repeat that as a fact. The firm figure is the top line pay: 5,000 for five logos at one credit per line.
Release dates are no better. SlotCatalog gives “around 2009” (marked approximate), VegasSlotsOnline says December 2015, and Igrosoft gives none.
Crazy Monkey or Crazy Monkey 2?
Igrosoft also made a sequel. Crazy Monkey 2 keeps the 5×3 grid, nine lines, mask wild and rope bonus, reworks the second bonus stage and adds symbols such as a frog, a toadstool and a tropical bird. If a lobby shows both, they are separate games with separate paytables; the Crazy Monkey 2 page puts them side by side.
Crazy Monkey on a phone
SlotCatalog lists the online build as HTML5, so it opens in a mobile browser on Android, iPhone or iPad without installing anything. The grid has only fifteen big symbols, which keeps it readable even on a 360-pixel screen, something many newer slots can’t claim. The free version and mobile play are covered on the demo page.
Where to play the Crazy Monkey slot online
There is no stand-alone Crazy Monkey game website or official app. The slot sits in the lobbies of online casinos that buy Igrosoft content, often through aggregators; SOFTSWISS, for one, lists Igrosoft in its game aggregator. Whether that casino may take your bets depends on where you live. In Mexico, look for a SEGOB permit. In Ukraine, the licence comes from the state agency PlayCity, and the minimum age is 21. In Russia, online casinos are banned outright. The casino checklist covers what to verify before a deposit.
