It's senior year at Horribilarum Sorcery Academy for Witty Witches and Wizards. All the hard work and studying comes down to this: the final exams! Under the helpful, tutelage of the Headmaster, players have learned how to handle volatile ingredients and turn them into fantastical potions! By pulling ingredients like Unicorn Tears and Fairy Dandruff, represented by marbles, out of the potion dispenser, the higher up ingredients slide down to fill in the gap. Players try to make the same ingredients smash together causing explosions and big turn combinations. Once all the necessary ingredients have been collected, players complete the potion for points and a special ability. The player with the most points graduates head of the class!
