Move one piece, or a straight line of your pieces. Move any clear distance up, down, left, or right. A group moves along its own line, never sideways.
To attack, your selected line must be longer than the entire enemy line ahead. You can approach from any clear distance, then shove the enemy exactly one square and stop. All the shoved enemy pieces are removed.
Immediately behind the enemy line there must be an empty square or the board edge. A piece in that next square blocks the shove.
Win immediately when only your color remains in the dark central squares. You also win if your opponent has no legal move. Central control is checked first. An empty center gives neither player a win.
On the board: select a piece, optionally tap a friendly endpoint to select a line, then tap a highlighted square to move. For a preview first, turn on Confirm moves in Game options: select your pieces, choose “Move selected pieces,” pick a highlighted destination, then confirm.
