Ultra

Ultra (or Time Trial) is a game mode where you play the game until the given time limit (usually 3 or 2 minutes).

The objective of this mode is simple: Score as many as possible in the given time limit. (Except for some games; see below)

If you top out before time runs out, the game ends instantly (except for Tetris Blitz, which removes the top 5 rows). In most games, your score will not appear in leaderboard for this case.

Some games allow players to choose level. In most games the level does not increase throughout the game.
