(Cauldron 15 Witch's Cauldron) is a trick-taking card game from Japan. Players are witches bringing different ingredients to brew up potions. Play follows the normal method for tricks. However, players are trying to reach but not exceed a total of 15. The cards players earn from winning tricks depend on the total value of the trick. If it is under or on 15, that's okay, but going over 15 causes trouble. Further, if the player's final score is over 15, they cannot win. But by obtaining all five ingredients, a player can neutralise the potion and discard to alter their score. The publisher has put English rules online. user summary
