Kuralin (Kurarin)

Game Rules: Draw one orthogonal loop and shade every cell it does not visit. The loop cannot cross, branch or revisit a cell. Circles touch one cell at a centre, two at an edge, or four at a corner. Black circles need more black than white cells; white circles need more white than black; grey circles need equal numbers. White cells belong to the loop. Tap a cell centre to toggle black; hold it to toggle a white dot. Drag between centres to draw. Tap an edge to toggle a line; hold it to toggle an exclusion cross. Repeat an action to clear its mark.

Frequently Asked Questions

How can I start solving Kuralin?

A grey circle on an edge touches two cells, so exactly one is black. Once one side is decided, the other side follows.
