Tetris
The classic falling block puzzle — clear lines, rack up points.
How to Play Tetris
Tetris is one of the best-selling and most recognisable video games of all time. Originally created by Alexey Pajitnov in 1984, it tasks players with manipulating falling geometric pieces called tetrominoes — each composed of four square blocks — to fill complete horizontal lines. When a line is completely filled, it clears and the player earns points. The game speeds up as levels progress, and it ends when pieces stack up to the top of the board.
There are seven distinct tetromino shapes (I, O, T, S, Z, J, L), each in a different colour. Clearing multiple lines simultaneously scores more points — clearing four at once (a "Tetris") is the highest-value single move. This implementation follows classic Tetris rules with wall kicks and increases speed every 10 lines cleared.
