Gems Bonanza Review
Gems Bonanza is a large 8×8 cluster game where coloured marks behind the symbols trigger five different features.
8×8 clusters
Five or more gems touching horizontally or vertically win and tumble away. Wilds appear only through the Wild Gem and Lucky Wilds features and can join several clusters at once.
Gems Bonanza Features
Coloured marks
Marks appear behind symbols on every spin, and a win on top of one triggers its feature once the tumbles end: blue clears the screen (Nuclear), pink turns one symbol wild (Wild Gem), brown adds 2×2 blocks (Squares), red adds a 3×3 to 5×5 block (Colossal Symbol) and green adds 5 to 15 wilds (Lucky Wilds).
Gold Fever
Exploding 114 symbols in one base-game spin starts Gold Fever. Every level plays all five features once, with a win multiplier of 2× at level 1, rising to 4×, 6×, 8× and 10× as you collect enough winning symbols to advance. It can be bought for 100× the bet.
RTP and maximum win
The demo reports 96.55%. The demo data doesn't state a win cap, so none is shown.
