Two rival artisans compete to lay mosaic tiles on a shared 7x7 stone slab. Place polyomino-shaped pieces spreading diagonally from opposite corners. When tiles enclose empty space, it is permanently sealed as void. The artisan who covers the most cells wins. How to Play

Open Matches
Goal: Cover more cells than your opponent on a 7×7 board.
Setup: Each player has 7 polyomino pieces (2 trominoes + 5 tetrominoes, 26 cells total). P1 starts from corner (0,0), P2 from corner (6,6).
Turn flow: Select a piece → Choose its rotation/flip → Place it on the board.
First piece must cover your home corner.
Diagonal rule: After your first piece, new pieces must touch your existing tiles at a corner (diagonally) but never share an edge with your own tiles.
No restriction against touching opponent tiles.
Sealing: When tiles enclose empty cells so they can't reach the board edge, those cells become permanently sealed void — no one can use them.
Passing: If none of your remaining pieces fit, you must pass.
Game ends when both players pass consecutively, or all pieces are played.
Winner: The player covering more cells wins. Equal scores = draw.
Tips: Place large pieces early, spread diagonally, and try to seal space near your opponent!
