Gameplay

Normal mode

Normal mode screenshot

This mode is described in the selection menu as "Regular Tetris", and plays similar to SEGA's 1988 version, with a speed curve which rises and falls.

To either side of the playfield is a pair of bars which slowly rise with the passage of time; clearing lines will fill the bars more rapidly. When the bars are completely full, the next tetromino locked will advance the player a level and empty the bars.

The amount of points awarded for line clears increases linearly from level 1 to level 10, and stays capped at 10.

• single: 100 × level points
• double: 400 × level points
• triple: 800 × level points
• tetris: 1600 × level points

Puzzle mode

Puzzle mode involves clearing lines to get a professor to the bottom of the playing field.

The player gets a time bonus based on the clear time. The maximum bonus is 20000 points (corresponding to 10 seconds or less) with 100 points subtracted for every 1/4 second over 10 seconds.
