Vexel is a clean, turn-based territory game where every move is about shape, space, and timing. You place polyomino pieces onto the board to claim territory and block opponents before they box you out.

The core rule set is intentionally strict. Your first piece must touch your corner. After that, your color can only connect at corners, never edge-to-edge. That single constraint creates most of the strategy.

Each color has the same piece bank, so advantage comes from placement order, rotations, and mirror choices. You can rotate and flip pieces every turn, undo when needed, and pass when no legal move remains.

You can play with 1 to 4 human colors and fill the rest with bots. The game ends when everyone passes in sequence, then scoring is based on covered tiles. It runs directly in the browser with no install.

Vexel is built as a self-contained web game and now lives directly on this site. Open the play page and start immediately.
