Morris

Morris is a classical game that existed as late as the Roman era and was especially popular in medieval Europe. The players place their pieces on the board one by one, and then move them on the grid. When three pieces are placed in a straight line, one of the opponent's pieces is captured.

The most famous version is Nine Men's Morris, which uses nine pieces for each, but Kanare_Abstract version also includes Twelve Men's Morris, which uses twelve pieces for each as well as the original variant "Stacking Morris" using a piece-stacking mechanism.
