Mystical Ninja Starring Goemon is an overhead Action RPG similar to Link's Awakening. Players explore towns, dungeons, castles and more, searching for treasure chests and attacking enemies. There are also shops and inns where you can purchase items or rest to recover your strength.

At the end of each level, there is a boss waiting for you. However, to defeat them, you must compete in a mini-game called 'The Surprise Match'. These mini-games usually feature button-mashing of some kind or a variation on a memory match game.
