Hive

Hive shares elements of both tile-based games and board games. It differs from other tile-based games in that the tiles, once placed, can then be moved to other positions according to various rules, much like chess pieces. Thus, the game has mechanics comparable to an abstract strategy board game and is marketed in that genre. It does not fit the classical definition, however, as there is no gameboard involved; the pieces are simply placed on some relatively flat surface.
