Both players take turns placing their ten pieces on the board one by one.
After that a piece may move one position orthogonally. It may capture by approach: after it moves, an enemy piece (or an unbroken string of enemy pieces) adjacent to it along its line of movement are taken. It may instead capture by withdrawal: if it begins its move adjacent to an enemy piece (or unbroken string) and moves directly away, the enemy piece(s) are taken.
Captures are multiple and mandatory.
The object is to capture all of the opponent's men. In case of repetive moves, the player with more pieces on the board wins.
