Tessera

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

Goal

Cover the most cells on a 7×7 board with your mosaic tiles. Highest score wins.

Controls

  • Select phase: Tap a piece shape card below the board to choose your piece and orientation
  • Place phase: Tap a highlighted cell on the board to place the piece at that anchor position

Key Mechanics

  • First placement: Your first piece must cover your home corner (P1: top-left, P2: bottom-right)
  • Diagonal growth: Subsequent pieces must touch your existing tiles at corners (diagonally adjacent)
  • No edge sharing: Your pieces may never share an edge with your own tiles (opponent tiles are fine)
  • Sealing: When tiles enclose empty interior space (cut off from the board edge), those cells are permanently sealed as void — neither player can use them
  • Piece supply: Each player has 7 pieces (2 trominoes + 5 tetrominoes, 26 cells total). Pieces can be rotated and flipped.

Win/Lose/Draw

  • Game ends when both players pass consecutively (no legal placements) or all pieces are placed
  • Win: Cover more cells than your opponent
  • Draw: Equal cell counts
