Spin the “Type Challenge Gen 1” wheel and land on one of the classic 15 types: FIRE, POISON, DRAGON, ICE, GRASS, BUG, ELECTRIC, GROUND, PSYCHIC, GHOST, NORMAL, FIGHTING, FLYING, ROCK, WATER. Fun fact: the very first games of the franchise featured exactly these types (before later generations added Steel, Dark and Fairy). You might use the wheel for a themed battle: spin once at the start, then each participant builds a team mainly of that type and faces off!
