Tap a tray stack, then tap an empty board cell to drop it.
Same colors flow together across the hex grid and pile up.
Stack 10 of one color to collect it — points, coins, chain combos.
Cascades expose colors beneath — chain clears for big scores.
Power-ups: Destroy, Move, Refresh tray, Undo. Earn charges from combos & levels.
Jam (no empty cells) and it's game over — spend a power-up to survive.
