GEMiX pays when at least five matching gems connect horizontally or vertically on its 7×7 board. Winning pieces leave the grid and more fall in. Each winning cascade helps fill a crystal meter, whose full charge can transform or remove symbols using effects such as Chain Lightning and Nova Blast.

The game also tracks three position patterns in each world. Clearing those patterns moves to a new world and awards its World Bonus. Miner, Princess and Wizard worlds have different Wild behaviour. That progression makes GEMiX more than a simple gem-reskin of Reactoonz: watch both the crystal charge and the current world pattern.
