Oroen

Oroen is a connection game for two players. The aim of the game is to connect two opposite sides: East-West or North-South. Two rules limit the play: 1) a piece can't have its top at the same height as a close piece. 2) it is necessary to leave the place for a piece if the piece is not at the top of the board. You have to comply with the two rules, if not possible only the second, if not possible only the first.
