1 frog 6 yellow and 12 green cylinders 1 dice with symbols The object of the game is to place the cylinders on the frog without the animal tipping over or one of the cylinders falling off. Rolling the dice determines the symbol on the end of the cylinder which is to be placed on the frog. A player that causes a cylinder to fall during their turn is out of the match. The winner is the player who put the last, and hence the most difficult, cylinder on the frog without knocking it over.
