Two Player Tetris

Play Two Player Tetris online — free co-op for two

Two Player Tetris is a free, browser-based block-stacking puzzle built for two people working together. Instead of racing each other on separate boards, you and a friend share one board and one team score. Create a room, send the 4-character code, and the game starts the moment your friend joins — no download, no account, nothing to install.

It plays like the classic falling-blocks puzzle you already know — 7-bag randomizer, ghost piece, a three-piece preview and one hold per piece — but every mode is designed around coordination: sharing space, splitting the controls, or taking turns. It's a quick 2 player game for a video call, a long-distance friend or a lunch break.

Six co-op modes

• Shared field — one 10-wide board, and you each drop your own pieces at the same time. Falling pieces pass through each other, then lock onto the same stack. Agree on who builds which side.
• Split field — the board is divided down the middle: Player 1 stacks in the left five columns, Player 2 in the right five. A row only clears when both halves are full, so you have to keep pace with each other.
• Garbage Survival — every 10 seconds a garbage row with a single gap rises from the bottom. Clear lines together faster than the garbage piles up; if the stack reaches the top, the round is over.
• Relay — one piece at a time, and control passes to your partner after every piece locks. Leave them a good spot for the next piece.
• Duo Controls — one shared piece with split controls: Player 1 moves it and hard-drops, Player 2 rotates and holds, and both can soft-drop. Talk constantly.
• Architect — the relaxed mode. Fill the dashed target shape together — ten targets, from a tiny block to a smiley face — for a bonus each time you complete one.

How to play with a friend

1. Open the page — you get your own room code at the top automatically. Click NEW ROOM any time for a fresh one.
2. Send the code to your friend. They type it under ENTER CODE and press JOIN. Each room holds exactly two players.
3. The game starts as soon as the second player joins. Either player can switch modes at any time, which restarts the round.
4. Move with ← →, rotate with ↑, soft drop with ↓, hard drop with Space and hold with C. WASD works too, and phones and tablets get on-screen buttons.

Scoring

Clearing 1, 2, 3 or 4 lines at once scores 100, 300, 500 or 800 points, multiplied by the current level. The level goes up every 10 lines and the pieces fall faster each time. Points go to the shared team score and to the player who placed the piece. In Architect, finishing a target shape adds a bonus of 500 × the Architect level. Your best scores are kept in the leaderboard on your device.

Is it co-op or competitive?

All six modes are cooperative: you play on one board, chase one team score, and win or lose together.

Can I play two-player Tetris on mobile?

Yes. It runs in any modern mobile browser, and phones and tablets get on-screen buttons for move, rotate, soft drop, hard drop and hold. A keyboard is still the quickest way to play.
