1 Stein + Co. (2003)

1 Stein + Co. is an abstract game with simple rules. Players take turns placing stones. The goal is to enclose empty squares on the board. Each square enclosed by a played block counts one point (Enclosed space must not be able to fit a block). The stones measure 2 x 3 x 4 squares and can be placed in any of the three alignments (i.e. covering 2 x 3, 3 x 4 or 2 x 4 squares). After the first stone is placed, subsequent stones must touch at least one previously placed stone - but cannot touch a stone with the same alignment (unless the player is able to score with the new stone). When the board is so full that no further stone can be placed, the player with the highest score is the winner. The rules offer a variant scoring system for three or four players, in which not only the active player scores, but also the player preceeding him/her.
