The Tetris guideline is the current specification that The Tetris Company enforces for making all new (2001 and later) Tetris games alike in form. A mode labeled "standard" or just plain "Tetris" will adhere to the Guideline more closely than other modes.
Current rules include:
- 22x10 cell playing field
- Tetromino colors
- Cyan I
- Yellow O
- Purple T
- Green S
- Red Z
- Blue J
- Orange L
- "Bag" randomization of tetrominoes
- Tetrominoes are generated 7 at a time as a permutation. [1] (There are 5,040 different such permutations.) This means that only 12 tetrominoes can come between one I and the next I, and a run of S and Z tetrominoes is limited to 4.
- Tetromino spawn locations
- The I and O spawn in the middle columns
- The rest spawn in the left-middle columns
- The tetrominoes spawn horizontally and right-side up.
- Tetromino rotation and lockdown behavior (see SRS)
