Match beside the hazard

A toxic tile clears when a resolved match is orthogonally adjacent to it. The matched elements never need to sit on the toxic tile itself — which turns the board into a targeting problem rather than a colour-sorting one. Clear every toxic tile before the moves run out.

Invalid swaps cost nothing, chain cascades are free, and the board reshuffles itself when no legal move remains.

Crystals, and what carries over

You earn one crystal per five thousand points, and crystals are shared across all three save slots. Unused moves carry into the next level; failing a level resets that bonus.
