Mid-loop

Game Rules: Mid-loop

Draw one loop through all the dots. Each dot lies halfway along a straight segment between two turns, whether it sits in a cell or on an edge.

Draw one closed orthogonal loop through cell centres and every black dot. It cannot branch, cross or revisit a cell; unused cells are allowed. Each dot is the midpoint of a straight segment between two turns, including dots halfway between cells. Tap an edge to draw or erase; hold to mark or clear an X. Drag between cell centres to draw a straight run; repeat to erase. Hold and drag to paint X marks. Sizes and counts follow the current settings and clues. Difficulty changes clues or deduction depth, never these rules.
