The Aztec-themed Gems Bonanza slot has an 8x8 grid layout with 64 symbols on the reels on each spin. To form a winning combination, you need a combination of five symbols anywhere on the grid, either touching horizontally or vertically.

It has a cluster pays mechanic, so any winning symbol combinations blast off the reels, and new ones drop in to allow multiple wins on any spin.

To set your stake, click the + and - buttons and choose the bet according to your budget.

The bonus feature is a free spins nuclear power feature. It comes with five various modifiers. They play in the following order of: Nuclear, followed by Wild Gem, then Squares, a Colossal Symbol, and lastly, Lucky Wilds. 

Every winning cluster fills the Gold Fever meter that activates the modifiers and has a 10x win multiplier. 

During the bonus feature, the wild symbol will form part of winning combinations, grow into a jumbo block, or act as a regular wild in the base game. 

You can also purchase the Gems Bonanza bonus feature up front for 100x your bet.

The top win on Gems Bonanza is 10,000x the bet. You can achieve this by reaching the Gold Fever bonus with the maximum multiplier in play. 

The symbols consist of various coloured gems, and the red gem is the highest payer, paying 1,000x the bet for 25+ on the reels.
