Mozaic ... two players take turns drawing stones, one at a time, from the bag and placing them on the empty board to form point-winning squares.
Four same-color stones in a square scores 4 points. Points are won with a player's own stones (even when placed by the opponent) and always accrued, never deducted.
Four exception stones are included: red = miss this turn, green = slide any stone diagonally to an empty adjacent tile, black = take two turns, white = remove any stone from the board and replace it in the bag. Exception stones are always returned to the bag after a turn.
The game is over when all the tiles on the board are covered, only the four exception stones remain in the bag and the highest score wins.
Using luck of the draw and strategy, players may place, move and/or remove opponent's stones, as well as their own, in order to win.
