==Timing==
Timing is based on video frames, which are approximately 1/70 of a second.
* [[Gravity]] makes a piece fall by one row every 20 - (level * 2) frames.
* [[Lock delay]] is 16 frames.
* [[Line clear]] delay is 20 frames.
* [[ARE]] is 2 frames.
==Scoring==
Placing a piece awards score according to the following formula:
* points = 4 + (2 * level) + row number of top of piece
The bottom row is number 1. If the piece was dropped manually, the position before dropping is used, so for a high score the player should drop as soon as possible.
If piece preview is enabled at the time a piece is placed, a 25% penalty is assessed: (both divisions are rounded down)
* points with preview on = floor(points / 2) + floor(points / 4)
No additional points are awarded for line clears.

One of the Tetris games Spectrum HoloByte developed before losing their legal battle with Nintendo.

Timing

Timing is based on video frames, which are approximately 1/70 of a second.

Scoring

Placing a piece awards score according to the following formula:

  • points = 4 + (2 * level) + row number of top of piece

The bottom row is number 1. If the piece was dropped manually, the position before dropping is used, so for a high score the player should drop as soon as possible.

If piece preview is enabled at the time a piece is placed, a 25% penalty is assessed: (both divisions are rounded down)

  • points with preview on = floor(points / 2) + floor(points / 4)

No additional points are awarded for line clears.
