About Tetris
Alexey Pajitnov designed Tetris in 1984 at the Computing Center of the Soviet Academy of Sciences. The name combines the Greek 'tetra' (four — the piece size) with tennis, his favorite sport. Pajitnov saw no royalties for over a decade; the rights moved through the Soviet government, then ELORG, then The Tetris Company, before he eventually earned a stake in the late '90s.

Tips
- Keep one column open as your 'I-piece slot' — you only clear a Tetris (four lines at once) when an I-piece drops cleanly down it.
- Don't fill rows from the center out. Fill from the edges and let the center be your insurance policy.
- Hard drops cost you nothing at low levels. At level 7+ they're survival.
