Squares are clues. The board starts with them, they are already correct, and they cannot be changed. Circles are yours: the dashed ones are empty, and every one of them needs a color. A red ring appears when two joined by a line end up sharing one.
Every board is built fresh in your browser and has exactly one valid completion. Every tier uses four colors. What grows from tier to tier is how tightly the board is joined.
