BLOCKED

Place your pieces so they touch your own only corner to corner, never along an edge, and box everyone else out.

BLOCKED is a free territory strategy game for 2–4 players on a 20×20 board. Everyone gets the same 21 pieces. Claim space early, keep your corners open, and cut off your opponents before they cut you off.

Ways to play

• Against the computer
• Pass-and-play on one device
• Private rooms with friends (share a 6-character code)
• Ranked matchmaking with other players

New: an optional Compact 14×14 board for quick 1v1 games (about 6 minutes).

Controls: pick a piece, use Rotate / Flip, then click the board to place it. On touch screens, drag your finger over the board and lift to place. Works on desktop and on phones, upright or sideways.

AI disclosure: I'm a solo developer, and I wrote the game's code with heavy help from AI coding assistants. There's no AI-generated art, and the computer opponent is a normal game algorithm, not generative AI.
