Mouse Island is a children's strategy game (Ages 5 and up) for two players created by Donald Green, the designer of Octi. In his words, "It's a game where mice scurry across a bed of dominoes in order to reach the cheese on the other side. On each turn, players move their mouse and a domino, so that the geometry of the island is always changing." The game contains all wooden components: ten two-space tiles (dominoes), two cheese disks, and two different mice disks.
