How Gemix works

Five or more symbols touching horizontally or vertically form a winning cluster. Winning symbols are removed, new ones drop in and the game cascades until no new win forms.

Crystal Charge

All wins in a round fill the crystal charge meter. When it is full, one of four effects is triggered: Chain Lightning, Light Beam, Crystal Warp or Nova Blast. Win on enough further symbols and the game becomes Super Charged, which multiplies the round's wins by 3.

The worlds

Each world has three patterns to clear by winning on marked positions. Clearing three patterns moves you to the next world and awards the World Bonus. Each world also has its own wild: up to 10 dropping wilds in the Miner's world, a spreading wild in the Princess' world and up to 8 sticky wilds in the Wizard's world.

What to look for in the demo

Watch the pattern marked on the grid. Wins on those positions move you forward even when the payout is small.
