Players aim to be the first to fill their cauldron in this mathematically educational game for children Ages 4 - 8. The ingredients cards each have a number on the reverse. When a player has his turn, he turns it over to reveal a number. Sum cards are spread out on the table. The player drawing an ingredient card, has to find a sum (using =,-, x) that equals the number on the ingredient. They then rub the "magic black ghost" on the back of the sum card. If that number equals the one on their ingredient, then they get to add that card to their cauldron board. You need 10 ingredients to fill your cauldron and win the game. You can play an alternative version whereby the sum cards are turned over one at a time and the ingredient cards are spread out on the table.
