Gameplay
If you pull the lever on a wrong number, all the numbers on the dial will be reset. Hurry, but be careful! — Lumina Flowlight (Advice), Sonic Shuffle
Each team must hack their way through a series of locked doors. The player on the left moves the analog stick in all directions to find the correct number from 1 to 8. When the correct number is found, an exclamation point appears above the player's head, and then the player on the right presses to open the door. If the team inputs the wrong number, they are shocked and must start the door over. Later doors have two or three numbers to find. The team that opens the most doors wins 20 Rings. If the teams have opened the same number of doors, both teams win the 20 Rings.
