Clock speed: 


  • R to start
  • A/W to rotate left/right
  • Left and right arrows to move
  • E to drop immediately
I recommend a clock speed of 1000 for an easy game, and 5000 for quite hard.

O's and X's:

  • A to start
  • Left and right arrows to select a square
  • R to place a piece

Game of life:

This is quite slow, so I suggest a clock speed of 40000 and some patience!
