Tether: A Polyomino Puzzle

Fill every light cell. Leave no uncertainty.

Tether is a calm, hand-crafted logic puzzle. Each board holds a set of rune-marked pieces and the altars they belong to. Slide every piece into place so the whole board is filled — no gaps, no overlaps. There is always exactly one way it fits, and finding it is the quiet joy of the game.
