Beschreibung
Looper is played on a toroidal board represented by a square grid. Only orthogonally adjacent cells count as adjacent. (Thus, there are no diagonal connections.)

On each turn, a player places 1,2 or 3 black stones on any vacant intersection. Alternatively, on his/her turn a player may announce "take", after which the opponent continues with white and the taker with black, alternately playing single stones onto empty intersections.

Black wins by making a global loop. White wins by preventing this. A global loop is a string of connected stones that circles the torus (either horizontally, vertically, or both horizontally and vertically) and connects back to itself.
