UGM is a fan game by LOst—developer of LTAP—featuring art and music by Simon Stålenhag. The title UGM is short for Unofficial Grand Master.


There are two modes, Master, and 20G. Gameplay rules seem to match those of TAP, such as having sonic drop and faster timings as the game progresses. However there is no evidence of a credit roll.

Unlike games from the TGM series, it is possible to attain the GM grade before reaching level 999.

The game has an account system, replays, and a developer console. It supports keyboard input and key remapping, or a fixed joystick layout.
