RTP Cluster Gems by Zillion Games is an 8x8 slot with 64 paylines, medium volatility and an RTP of 95.05%. The game uses cluster win mechanics, where symbols must connect on at least one side to form a winning group. Wild symbols can join multiple clusters at once and substitute for any symbol except the scatter.
The feature set includes a re-spin mode with a multiplier that increases after each re-spin, while winnings are added together during the sequence. A randomly activated Star Bomb feature is also part of the gameplay. Five scatter symbols trigger free spins, with additional free spins available if five scatters land again during the bonus round.
This demo version lets players play for free and practice before playing for real money. The game includes a story win interface that records cluster sizes and winnings during re-spins, then resets after each spin. Bet sizes range from 0.10 to 100.00, and the maximum win is 3000x.
