The swimming ring is placed into the water, players receive all discs of one colour. In his turn a player drops one of his discs into the water, it schwims either showing Nessi or the empty side. Then the next player drops a disc, if it hits another disc in the water, this is turned over. When all discs have been dropped, the player with the most Nessis visisble on his discs wins the game. In a variant one can end the game when the first player has 5 Nessis showing.
