Objective

Be the last player who can still move. The board shrinks every turn — trap all of your opponent's pieces and you win. There are no draws.

Each turn: move, then destroy

1. Move one of your units (a stack of 1–3 pieces) up to as many tiles as its height, along present unoccupied tiles.
2. Destroy any one present, unoccupied tile anywhere on the board — it's gone for good.

In fixed-start games the very first turn is move-only (no destroy).

Stacking & splitting

Merge: move onto a friendly unit to combine them (max height 3). Split: peel one piece off a stack of 2+ onto an adjacent empty tile — uses the whole action. Taller stacks move farther, and can jump over holes, rubble, and shorter enemies — reach equals their height.

Win condition

You win when none of your opponent's units can move, merge, or split at the start of their turn. Boxed-in units turn grey; a counter by the turn indicator shows how many of yours can still move.
