YMMV / Nazo Puyo

• Nintendo Hard: The more challenging Nazo Puyo puzzles delve into gameplay quirks that casual Puyo Puyo players rarely encounter in normal gameplay, such as the "ghost" 13th row, climbing up stacks by rotating, and wedging in Puyo by exploiting the Puyo's "pivot". Once Compile began to run low on puzzles using the standard Puyo Puyo (1992) ruleset, they added new exclusive mechanics with gravity-defying Blocks and unclearable Iron Puyo, the former adding a dexterity challenge on top of the planning aspect of the game.
• Older Than They Think: Arle no Roux had a Doppelganger Arle as the final boss years before Puyo Puyo~n did the same thing.
