In Tinkle Pit, an evil wizard spawns monsters in a tiny village. The nameless protagonist of Tinkle Pit chooses to go on a world-saving quest to defeat the wizard and his minions. He is accompanied by an oversized, anthropomorphic sleigh bell as his weapon. The plot of Tinkle Pit is a minor, negligible component of the game. Though the game's storyline (written in Japanese) is likely incomprehensible to most foreigners, the game itself (which employs mostly English text) is quite readable.
The game is divided into 8 worlds. The first one has 4 rounds, and every other one has 6 rounds.
The player walks around a maze collecting items while accompanied by a disproportionately sized sleigh bell. The player has the ability to drop the bell, which is invulnerable to the enemies, and move around by pressing the A button, therefore creating a line between him and the bell. Releasing the button makes the bell come back to the player; enemies are killed by having the bell slam into them. There are also balls of power that can be picked up. By pressing the B button, the player can throw them at the enemies - they will bounce off the walls until they hit one. Killing all enemies in a maze advances the player to the next stage.
