Tetris Plus

Tetris Plus is a Tetris variant produced by Jaleco in 1996 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 competitve version of Puzzle Mode.

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: The scoring for level 0 is the same as for level 1.
 * single: 100n points
 * double: 400n points
 * triple: 800n points
 * tetris:1600n points


 * Speed levels, in frames per row:


 * 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.
