Gems Bonanza: an 8x8 cluster slot, high volatility
On the 8x8 grid, a win forms when five or more matching symbols touch horizontally or vertically. The Aztec, Gems and Treasure theme frames the game, and seven symbols, from red ruby to blue gem, make up the symbol set. Each winning cluster clears, and new symbols tumble into the gaps, so one spin can chain several wins. Gems Bonanza is a high volatility game, so its wins come rarer and bigger.
When a win lands on a random coloured mark, one of five spin modifiers can trigger: NUCLEAR, WILD GEM, SQUARES, COLOSSAL SYMBOL or LUCKY WILDS. Collect 114 winning symbols in a base spin and the Gold Fever bonus round opens. Its five levels raise the win multiplier from 2x to 10x, and each level plays all five modifiers once, in fixed order.
