Jeff's Gems Features & Bonus Games
The special features of this Twist Gaming online slot make the gaming experience action-packed. Here’s what you can expect when spinning the reels:
Cascades
When winning combinations occur, the contributing symbols disappear, causing the remaining symbols to cascade downwards. New symbols then fill the gaps, offering additional chances for wins. You can learn more about this cascading reels feature over on our blog.
Wild Symbol
The Wild Symbol substitutes for all other symbols except Scatters and Prize symbols, making it valuable for forming wild feature-winning combinations and a thrilling opportunity for lucrative payouts.
Prize Symbol
Prize Symbols display random multiplier options ranging from 1x to 200x. If a Prize Symbol lands on a Backer, the prize is multiplied by the Backer's value. In the Drop Bonus, the top multiplier can reach up to 500x.
Burst Symbol
The Burst Symbol can land anywhere on the reels and creates Backers behind its position (2x multiplier) and adjacent positions (1x multiplier) while also awarding a re-spin. These re-spins stack, and the total is shown next to the reels. Backers can increase up to 5x in the Base Game and Dungeon Bonus or (up to) 10x in the Drop Bonus.
Sticky Symbol
During the Free Spins bonus round feature, any Backer symbols that land become sticky, remaining in place to boost the player's chance of winning.
Free Spins Feature & Scatter Symbols
Land 4 Scatter symbols to unlock the Dungeon Bonus, which awards 8 Free Spins. Scatter symbols also allow retriggers, awarding 2 additional spins for every 2 extra Scatters during the free spins round. Backer symbols become sticky during the bonus and remain in place until the feature ends.
The Super Free Spins Drop Bonus round awards 3 spins with randomly placed Burst Symbols on the board. Prize symbols drop on the board during each spin, and prizes landing on Backers are awarded. More Burst Symbols can be added at the beginning of each spin to enhance your winning potential.
Bonus Buy Options
The most lucrative feature of Jeff’s Gems is the Bonus Buy features. Players can instantly gain access to the Free Spins and Super Free Spins features as follows:
Buy Bonus = 100x the bet

Super Boost
For 5x your bet, the Super Boost buy feature guarantees Scatter symbols on every spin, massively increasing the chance of landing free spins.
Bet Sizes, Max Win & Return to Player (RTP)
Play Jeff’s Gems by wagering between 0.10 and 1,000.00 per spin, which are flexible betting limits. The outcome of each spin is completely random and fair, as this software provider uses a random number generator (RNG) built into the mechanics.
With a theoretical return-to-player percentage (RTP) of 97%, every slot machine spin holds winning potential. The volatility of slot machines varies, and this one offers a medium volatility experience with a 3% house edge. The max win is set at 10,000x your bet, making it one of the market's most rewarding online slot games.
