Tetris Plus is a Tetris variant produced by Jaleco in 1995 for their Jaleco Mega System 32 arcade hardware. The game includes two single player modes, Normal Mode and Puzzle Mode, as well as a two player VS Mode which plays like a competitive version of Puzzle Mode.

On November 1st, 2019, it was re-released on the AtGames Legends Ultimate Arcade.

Normal Mode

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 from then on remains constant. For a given level, n, between 1 and 10, the points awarded are as follows:

• single: 100n points
• double: 400n points
• triple: 800n points
• tetris:1600n points

The scoring for level 0 is the same as for level 1.

• Speed levels, in frames per row:

Level	Easy	Normal	Hard	Hardest
0	50	50	50	50
1	25	20	16	16
2	20	14	10	10

• Lock delay remains constant at 15 frames.
• DAS has an initial delay of 10 frames, and a repeat rate of 20Hz.

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.
