This is a simple game of quick counting and memory for children. Six dice, each with some sides showing fish and some just water are rolled. The first player to place their hand over the tile with the correct number of fish on it wins a glitter fish. But there are two tiles for each number with different backs, one has a whole net the other a net with a hole. You only get a glitter fish if you identify the tile without a hole in the net. The winner is the player with most glitter fish at the end - BoardGameGeek
