Pattern No. 1

Rangoli

Sun 1 NovSunday · 7×7

Tap a tile to turn it a quarter turn clockwise. When every line meets a line on the next tile, and none runs off the floor, the rangoli closes into loops and fills with colour.

Each quarter turn is a tap; par is the fewest possible. A tile's lines glow once all of them join up. Arrow keys move, Space or Enter turns.
