Out now




Joker Rainbows is a 6×4 reel slot with 40-paylines and a maximum win of up to x50,000 the player’s bet. 




92.96 – 96.13 per cent


Low value symbols are represented by cherries, plums, grapes, watermelons, clovers and bells. These symbols can offer between x0.1 and x2.5 the player’s bet, depending on the amount of matching combinations that land on a single spin. 

Single, double and triple-stacked bars depict the high value symbols, alongside a lucky number seven. If the correct number of paying combinations land in one go, these symbols can offer between x0.25 and x25 the player’s preferred stake. 

Standard wilds can appear on the reels, coming in the form of a yellow joker. These wilds substitute for all symbols other than the cashpot collect chips and bonus star scatter. 

Multiplying wilds can also appear, with their multiplier values depending on the HyperBet game mode that the player has activated.

These bonus star scatters can drop into play on any reel, triggering the free spins feature if three or more land on the same spin. Landing two or three scatters at once will also award payouts of x2 or x10 respectively. 

Finally, cashpot collect chips are available, awarding payouts between x25 and x50,000 depending on the amount of cashpot symbols that land in one go. 


Throughout the game, players can choose to use Kalamba’s HyperBet feature which increases their stake in order to access wilds with higher multipliers, higher volatility and more free spins in the bonus game mode when it is activated.

Firstly, players can choose to play the standard game mode, in which multiplier wilds that land on the reels will only have a value of x1, and activating the free spins feature will only provide five spins. 

Alternatively, players can increase their stake size by 55 per cent to see wilds appear with x2 multipliers and gain seven free spins when the bonus game mode is activated. 

Next up, players can increase their stake by 115 per cent to gain x3 multiplier wilds and have nine free spins. Lastly, players can increase their stake by 400 per cent to gain x10 wilds with 12 free spins in the bonus game mode. 

During the free spins, bonus accumulator symbols can appear, represented by a ‘+3’. Landing three of these throughout the game mode will award an additional three spins. 

Furthermore, players can buy access to the free spins game mode with five, seven, nine and 12 free spins options for respective prices of x65.75, x113, x167.5 and x372.5 their preferred stake. 


Alex Cohen, COO and Co-Founder at Kalamba Games, commented: “Providing a vibrant aesthetic within a classic fruit style slot emphasises the combination of traditional themes contrasted with innovative features that Joker Rainbows has perfected and will inevitably appeal to a wide array of slot enthusiasts.

“Offering the ability to change the slot’s wild multiplier value provides a lot of replayability whilst the combination of free spins and cashpots boosts player engagement. With a huge max win of x50,000 on offer, we are thrilled to see the reception this colourful title receives upon release.”
