Puyo Pop brings the puzzle tower gameplay of Puyo Puyo Tsu to Western audiences. Rather than a linear story mode, the main experience drops Arle Nadja into a randomized challenge tower where each floor requires reaching an EXP threshold by defeating a roulette-selected roster of opponents. Miss the goal after clearing all challengers and a bonus opponent appears — fail again, and Arle is eliminated. EXP requirements vary across platform versions: the Super Puyo Puyo Tsu release demands double the points on the first floor compared to the arcade and Mega Drive editions.
