Play Tetris online in your browser: rotate falling tetromino blocks, stack them cleanly, clear complete lines and survive as the speed rises. If you remember the game as a falling blocks game, falling brick game, block stacking puzzle, line clear game or old brick game, this is the same classic idea with modern controls and no download.
Tetris is the best-known falling block puzzle: seven four-square pieces drop into a vertical well, and your job is to rotate, move and stack them before the board fills up. A complete horizontal row disappears as a line clear, giving you more room to keep playing. This version runs directly in the browser, so it works on desktop, tablet and mobile without an app install.
Players search for this kind of game in different ways. Some type Tetris online or classic Tetris; others remember it as a falling blocks game, falling block puzzle, block stacking game, falling brick game, brick game online, clear lines game, tetromino game or tetrimino game. The core intent is the same: stack shapes, clear lines and chase a better score.
On desktop, Left and Right move the piece, Down soft-drops, Up or X rotates clockwise, Z or Ctrl rotates counter-clockwise, Space hard-drops, C or Shift holds a piece, and P pauses. On phones, touch buttons appear below the board for movement, rotation, hold, soft drop and hard drop.
Infinite mode is the classic endless 10x20 board. The speed rises as you clear lines, so the challenge shifts from simply surviving to making clean wells, planning the next pieces and scoring before the stack reaches the top. Signed-in players can save their best Infinite score and compare it on the Tetris leaderboard.
Levels mode gives the falling blocks formula a progression loop. Each level has its own line goal, speed and board setup, so short sessions still feel meaningful. The level parameters are generated from the level number, which keeps the challenge consistent and makes leaderboard progress fair for everyone.
The game includes the features people expect from a modern Tetris-style browser game: a hold slot, ghost piece, hard drop, soft drop, next-piece queue, 7-bag randomizer and SRS-style wall kicks. These tools make the game easier to read for beginners and more strategic for players who want combos, clean stacking and T-spin setups.
Signed-in players can compete for the best Infinite score and highest Levels progress. XP and coins earned from Tetris are shared across CPSCount, so time spent on puzzle games still contributes to the same account progression used by the site's click tests and other games.
