Tetris is the puzzle game that defined a genre. Created by Soviet engineer Alexey Pajitnov in 1984, it weaponized a deceptively simple idea — rotate and slide falling shapes into solid rows — into one of the most addictive feedback loops ever designed. Within a decade it had conquered arcades, the Game Boy, and basically every device with a screen.
Every piece is one of seven tetrominoes, each made from four squares: the long I, the square O, and the T, S, Z, J and L pieces. They drop from the top of a 10-wide playfield, and you have a fraction of a second to choose where each one lands. Fill a complete horizontal row and it disappears; survive long enough and the gravity speeds up.
The score system rewards big plays. A single line gives you a tiny payout, but clearing four lines at once with a vertical I-piece — the legendary Tetris — pays out thirty times more. The deeper you go, the faster pieces fall, until even a one-second pause means a tower spilling into the top of the board.
Falling tetromino pieces appear at the top of a 10-by-20 grid. You move, rotate, and drop them to fill complete horizontal rows. Every full row disappears and earns you points. Game over comes when a new piece can no longer fit on the board.
Clearing four rows simultaneously with a single piece — almost always the long I-piece — is called a Tetris. It pays out 1200 × (level+1) points, by far the highest-value line clear in the game.
The hold slot lets you stash one piece for later. Press C (or the hold button) to swap the falling piece into hold. You can only hold once per piece — you have to lock the next piece before you can swap again.
Every 10 lines cleared advances the level by one. Higher levels make pieces fall faster, which means more pressure but also more points per line clear (line scores are multiplied by level + 1).
The semi-transparent outline at the bottom of the board shows exactly where the current piece will land if you hard-drop. It's there to help you place pieces accurately without guessing.
Yes. Your highest score is stored in your browser and persists between sessions, even after closing the tab or restarting your device.
A T-spin is when you rotate a T-piece into a slot where three of the four diagonal corners around its centre are already filled (walls count). The game detects the rotation and pays out a big bonus: 800 × (level+1) for a single, 1200 for a double, 1600 for a triple. A purple "T-SPIN" popup floats over the clear.
Every time you clear lines in two consecutive locks, your combo counter goes up. Each clear after the first earns an extra 50 × combo × (level+1) points. Drop a piece without clearing anything and the combo resets to zero. The popup shows the multiplier — "x3" means three clears in a row.
Back-to-back. Two consecutive "difficult" clears — a Tetris (4 lines) or any T-spin — multiply each other's score by 1.5. Mixing in a regular single, double, or triple breaks the chain. You'll see a "B2B" label on the popup whenever the bonus fires.
You earn one coin for every 40 points you score, and coins are saved in your browser between games. Open the Themes menu from the start screen to spend them on alternate block palettes — Neon, Sunset, Mono and Candy. Themes are purely cosmetic: they change the colors only and never affect scoring or difficulty.
