In turn, each player must spin the roulette wheel and draw the color and amount of thorns to pull from the hedgehog. Hint: The player must choose the thorns in the middle and take them very carefully so that the hedgehog does not fall. If the player knocks out the spine and the hedgehog does not fall, the turn passes to the next player. If the hedgehog falls, the player ends the game turn. The other players set up the game again and continue for another turn. Continue in this manner until only one player remains. He/she will be the ultimate winner of the game.
