Goal. Capture all of your opponent's pieces, or block them so they cannot move.

Moving. White moves first. A regular piece moves one square diagonally forward. A king slides across multiple squares.

Capturing (mandatory!). If you can capture, you must. A regular piece captures both forward and backward. A king captures from a distance and lands freely behind the captured piece. You must always take the sequence that captures the most pieces.

Becoming a king. If your piece reaches the far row and stops there, it becomes a king (♛).

Controls. Tap your piece — the possible squares light up green. Pieces that must capture glow pink. Tap a green square to move.
