Tetris Plus^[a] is a Tetris variant produced by Jaleco in 1995 for their Jaleco Mega System 32 arcade hardware. In 1996 ports were released for the Sega Saturn and PlayStation, as well as a Game Boy version. 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. A sequel, Tetris Plus 2, was released in 1997.

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

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.^{[scoring 1]}

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

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

Lock delay remains constant at 15 frames.
DAS has an initial delay of 10 frames, and a repeat rate of 20Hz.
IRS is bit weird with this game, If you press rotate button During Entry Delay, the piece will not rotate until entry delay ends, and rotate sound does not play. You can't IRS while holding down rotate button (or if you are on console version). Only arcade version has this issue.

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.

Vs. mode

Initial Playfield State

There's a Initial Playfield State Which cycles 10 Playfield States and loops. Does not persist after machine reboots. (marked x is professor's spawn location)

Playfield 1,

Playfield 3

Playfield 4

Playfield 5

Depending on the console/machine, It has weird quirks around games, Only Game boy version gives a draw, (excluding game boy) Leaving no control results in a P1 Win (P2 win in console), (excluding game boy) Holding down results in a P1 Win.
