Place one dark stone on an empty space; the white stone then moves one space. Enclose the white stone before it slips off the edge of the board.
Fewer stones placed means a higher score. Three escapes ends the game.

The rules. This ruleset descends from Chat Noir, a 2007 browser game by Taro Ito of gamedesign.jp, in which a cat is fenced in on a hex grid — cloned endlessly since as Trap the Cat and Circle the Cat. The underlying idea — contain a runner by placing one blocker per turn — is older than any of them; mathematicians have studied such containment games at least since John Conway's Angel Problem (1982). Talos restates the puzzle in the language of stones.
