Loop Formation

A bridge puzzle: connect numbered islands with horizontal or vertical bridges so each island has as many bridges as its number. Two islands share at most two bridges, bridges never cross, and all islands must link up.

A pearl loop puzzle: draw one simple loop through cell centers that visits every white and black circle, obeying straight/turn rules that differ by color.

Connect each pair of matching numbers with a path; paths can’t cross, branch, or pass through other numbers.

A loop logic puzzle: connect dots into one simple closed path whose edges match the 0–3 clues in adjacent cells.

Shade cells as the arrow clues indicate, never side by side, then draw one loop through all remaining empty cells.
