Joker Rainbows Overview

Joker Rainbows is a fruit slot from Kalamba Games, launched on 6 April 2023. It uses a 6x4 grid with 40 paylines. Kalamba’s official game sheet rates its volatility 10/10, with a maximum win of 50,565x and a hit frequency of 17.1%.

Symbols and Line Pays

SlotCatalog lists ten regular symbols: cherries, plums, grapes, watermelons, clovers and bells at the low end, and single, double and triple BARs and red lucky sevens at the top. At a bet of FUN 1.72, six bells or six clovers pay 2.00, and six watermelons, grapes, plums or cherries pay 1.20. Three of any of these pay 0.08.

Multiplier Jokers

The Jokers are wilds that appear on reels 2 to 6 and carry a multiplier. On our screenshots they show x3. One spin with several of them on the grid paid 6.48. SlotCatalog notes that the multipliers of several wilds in one win are not added together.

HyperBet

Kalamba’s HyperBet lets you choose the wild multiplier – 1, 2, 3 or 10x – together with the starting number of free spins. Our session used x3 and 9 free spins. SlotCatalog adds that the RTP changes with the level, from 92.96% to 96.31%.

Cashpots and Free Spins

Four Cashpots sit above the reels: Platinum 40,000.00, Gold 4,000.00, Silver 400.00 and Bronze 20.00. According to SlotCatalog, 10, 12 and 15 bonus symbols on the middle reels award Silver, Gold and Platinum. Three star scatters start the free spins, and every three scatters collected add 3 more spins. Buy Bonus offers four entry options.

A Look at the Grid

One of our screenshots shows the whole sixth reel covered by Jokers, a golden BONUS star on reel 4, and sevens, BARs, plums and grapes on the other reels. A Big Win Replay panel on the left lists recorded wins of x23,316, x10,025 and x5,111, which gives an idea of how far a strong round can go.

Who It Is For

Kalamba’s own description sums the game up as classic fruit symbols with modern extras: four Cashpots, Multiplier Wilds, Buy Bonus, HyperBet, free spins and a gamble. It is a very high-volatility game for players who accept long dry spells in exchange for the Cashpots and the big multiplier rounds.
