Tilt-o-Tube is a multi-player mini-game in Club Penguin Island. It was added in the 1.5.0 update, and can be played at the Beacon Boardwalk. It is accessed from a buoy in the middle of the bay that transforms into the platform the game is played on every three minutes.
After the buoy transforms into a platform, a small trampoline between the platform and the row of icebergs at the south end of the boardwalk appears. Members can then interact with the trampoline to access the platform. After 30 seconds, the trampoline disappears and the game starts. Players have to bump into others on their tubes, trying to knock them off the platform, while trying not to fall off themselves. However, the platform is constantly rotating and tilting during the game, and eventually shrinks in size as well. If a player falls off, they are out of the game. After all players fall off the platform, the game ends, and the platform rises out of the water and flies away. Players do not receive anything for success during the game, even if they are the last one on the platform.
After the game became available to non-members, the instructions still said the game was for members. Also, on the CPI Phone, the Tilt-o-Tube live event could not be accessed by non-members, as the "GO!" button was locked. These issues were fixed in the 1.11.0 update.
