Tetris

How to play

• Press Start Game. Tetrominoes fall one at a time; fill horizontal lines to clear them and earn points.
• Use Arrow Left / Right to move, Arrow Down to drop faster, and Arrow Up to rotate. On touch, use the on-screen Left, Right, Down, and Rotate buttons.
• When a piece locks, if it stacks to the top spawn row, the game ends and your Score is shown.
• Cleared rows add to your score; plan gaps so you can complete full lines without trapping yourself.

Game description

Pieces fall one at a time into a vertical well. You shift them sideways, rotate them to fit, and lock them into place when they land. Complete horizontal rows clear away and give you breathing room; let the pile reach the top and the round is over. Every placement is a small packing puzzle where a single awkward gap can haunt you ten drops later.

This browser build mirrors familiar expectations: move left and right, drop faster when you need gravity’s help, rotate to rescue tight fits, and read what comes next when a preview is shown. Touch players get matching buttons so the same rules travel from laptop to tablet. Sessions reward foresight—building stair-steps for the long bar, carving stable platforms, and recovering calmly after a bad lock instead of slamming keys. The score quietly rewards consistency more than luck.
