From Rosetta Code
Tetris is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Create a playable Tetris game.

The visible game matrix should be 10*20.

It must have:

  • left/right key;
  • a hard drop key (the current piece will be dropped and locked at once);
  • (better with another soft drop key);
  • at least one rotation key;
  • (better with two, for both clockwise and counter-clockwise 90° rotation);
  • full set of 7 kinds of shapes (ITOSZJL).

The piece should be rotatable at its initial position (unlike sega arcade tetris), and automatically falling at reasonable speed.

At least 1 preview piece should be shown.

No further requirement about randomizer / rotation system / DAS / colors / difficulty levels / score / hold, but you may do it if you wish.
