The playfield is viewed from the side, with each player managing a vertical well. Pairs of colored gems fall from the top; move and rotate them to form groups of four or more matching gems. A Crash Gem removes a connected group of its color and can trigger a chain reaction.

Single-player play follows a sequence of character battles, while versus play pits two players against each other. Cleared gems create colored nuisance blocks on the opponent’s field. Plan stacks so one break starts another, manage the rising pile, and use counterattacks before the well becomes full.

Build small, controlled color groups while watching the next pieces. Avoid filling the center of the well with isolated gems, because they can block future chains.

• Save Crash Gems for large groups or chain setups rather than clearing immediately.
• Watch the opponent’s nuisance-block pattern and prepare counters when a large attack is incoming.
• Keep the stack low enough to preserve time for rotation and placement decisions.
