Isabella

Isabella, the little witch, is brewing a magic potion. She is throwing all kinds of ingredients in her cauldron. Sometimes she forgets whether an ingredient is already in her cauldron or not. Help Isabella to remember and score wizard hats in return. Each turn ingredients are placed in Isabella's cauldron. You can score a wizard hat if you can remember which ingredients are in her cauldron. The player with the most wizard hats at the end of the game, wins the game!
