Pentris

Each player get a 10x10 squares grid. Two Tetris-like pentominoes are associated with each numbers 1 to 6. The game is played in real time: a dice throw determines a combination of two pentominoes, each player must choose one and draw it on his/her sheet connected to the bottom or on top of preexisting full squares in a gravity-affected fashion. The shapes can be rotated at will before being drawn. At the end of the round, player rotate their sheet 90° clockwise. Repeat until every player can't place a piece during a round. The number of completed columns OR rows gives the score. The player(s) with the highest score win(s).
