Super Puyo Puyo 2 replaces the original game's linear campaign with a tower-climbing mode where Arle Nadja selects opponents by spinning a roulette. Each floor of the tower carries a required experience-point threshold that must be met to advance; if all available opponents are defeated without reaching the target, a hidden final challenger appears. Failing to hit the quota after that last match ends the run. Experience requirements vary between the arcade, Mega Drive, and Super Famicom releases—the Super Famicom version demanding twice the points on the first floor alone.
