Loop — Connect the Dots Logic

melncoly

About this game

Loop is a calm, offline logic puzzle about one simple idea: connect all the dots into a single closed loop.

Draw horizontal and vertical lines between the dots so that every dot is joined by exactly two lines, forming one continuous loop with no loose ends and no branches. A few pink lines are given to start you off — they're always part of the solution, so you can reason out the rest, one deduction at a time.

No timers, no pressure, no noise. Just you and the puzzle.
