Be the first to cast the magic spell in the cauldron! To prepare the game, build the shelf, ingredients, and special die from Lego pieces and place the 16 ingredients (4 ingredients for each of the four colours) on the shelf. On your turn, place the owl above a column or beside a row of the shelf, then roll the special die to see which ingredient you can take from the owl's column or row. If you roll black, steal an ingredient from an opponent. The first player to acquire ingredients in all 4 colours casts the magic spell and wins.
The game comes with a few optional rules and encourages players to make their own rules.
