  • move left/right:

    • out of matrix -> (OutOfMatrix, falling)
    • collision -> (Collision, falling)
    • ok -> (Ok, next)

  • rotate left/right:

    • out of matrix -> (OutOfMatrix, falling) -> move left/right + rotate left/right
    • collision -> (Collision, falling) -> move left/right + rotate left/right
    • ok -> (Ok, next)

  • move down: *

spawning: * I, size 4, (10 - 4) / 2 = 3 -> offset = (3, 0) * L, size 3, (10 - 3) / 2 = 3 -> offset = (3, 0) * O, size 2, (10 - 2) / 2 = 4 -> offset = (4, 0)

rotateTwice: (0, 0) (0, 1) (0, 2) (2, 2) (2, 1) (2, 0) (size - row, size - col) (1, 0) (1, 1) (1, 2) (1, 2) (1, 1) (1, 0) (2, 0) (2, 1) (2, 2) (0, 2) (0, 1) (0, 0)
