Each turn has exactly 2 steps:
Step 1, Move: Select one of your pieces, then click an adjacent square (including diagonal). Capture an enemy by moving onto it.
Step 2, Block: Click any empty square to place a wall. Walls block movement.
Line strike (weapon): When a row or column is completely full, it fires. You score +1 point per fired line. Only enemy pieces on that line are removed. Your pieces stay. Blocks stay.
Blocks reward: Regain +1 block per fired line. If a strike removes 2 or more enemy pieces (total from that strike event), gain +1 extra block.
Win by: reaching 5 points, capturing all enemy pieces, or leaving the opponent with no legal moves.
Undo: One undo available per turn. Reverts your last action within the current turn.
