85.75-95.49 per cent


Low value symbols are represented by cherries, lemons, oranges and plums. If the right number of matching combinations land on a single spin, these symbols can offer between x1 and x5 the player’s bet. 

Meanwhile, grapes, watermelons and bells depict the medium value symbols, providing wins between x10 and x20 the chosen stake. 

High value symbols come in the form of red lucky sevens, offering x50 the player’s preferred bet for a three-of-a-kind win. 

Pearl symbols can also appear, displaying either monetary values from x1 to x100 the player’s bet or jackpot values of minor (x10), major (x50) or maxi (x250). 

All of these symbols will appear double-stacked in reels, but this has no influence on payout prizes. 


Landing three pearl symbols on the same spin will trigger the hold-and-win game mode. 

In this game mode, players are given three spins to land as many pearl symbols on the reels as possible. 

As the pearl symbols appear double-stacked, the reels will expand to be 6×3-sized, allowing for a total of 18 individual pearls to appear in the feature. 

Each pearl that drops into play will reset the number of spins to three, and as the game draws to a close the player will receive the accumulated value of all pearls that appear, including jackpot pearls. 

Finally, if players land a full board of 18 pearls, the mega jackpot worth x1,000 will be awarded. 


David Mann, Chief Executive Officer at Swintt, stated: “While our SwinttPremium slots have certainly proved a huge hit with players, one feature that undoubtedly stands alone in terms of its popularity is the pearl feature – and in Jackbox Pearl Upgrade, we’ve taken this exciting bonus round to all-new heights!

“Now, not only can players collect instant cash prizes, local jackpots and gigantic full table wins, but any purple pearl symbol that appears has the power to upgrade all collected payouts even further. 

“As such, we expect this innovative twist on the classic pearl feature mechanic to be a major success with new players and existing premium fans alike when the slot goes live at our partner casinos this month”
