Loopy Loop Puzzle Unblocked

Loopy Loop Puzzle starts with a field of dots and scattered numbers and asks for one thing: a single closed loop drawn along the lines. The numbers say how many sides of each cell the loop uses. On a plain square grid that is already a solid workout, but this version goes much further, letting you play the same rules on triangles, hexagons, Cairo pentagons and tilings that never repeat. Mike Pinna wrote it for Simon Tatham’s puzzle collection, with Lambros Lambrou adding the exotic grids. It runs unblocked here on any device.

Lines, Crosses and the One Big Rule

Every edge begins yellow, meaning undecided. Click it to make it black, which puts it in the loop. Right-click, or press and hold, to cross it out when you know it is not part of the loop. Clicking again returns an edge to yellow.

The finished drawing has to be one ring. It cannot cross itself, it cannot split at a dot, and two separate rings do not count even if every number is happy. Each numbered cell needs exactly that many black edges around it. Empty cells can have any amount. The board flashes when you get it right.

Out of the box you get a 10x10 square grid on Easy. The Type menu offers square grids at Easy, Normal and Hard in two sizes plus a long list of other tilings at Hard. Custom pairs any grid with any size and with Easy, Normal, Tricky or Hard.

Deductions That Carry Over Between Grids

The neat thing about Loopy is that a few local rules work on every shape.

Zeros are free information. None of a 0’s edges are used. Cross them all out first.

Every dot has degree zero or two. If a dot already has two black edges, every other edge at that dot is out. If it has one black edge and only one undecided edge left, that edge must be black.

Maximum clues bite hardest. On squares, two 3s side by side must use the edge between them plus both outer edges parallel to it. A 3 in a board corner always takes the two outer sides.

Avoid tiny rings. Closing a small loop early is always wrong unless it is the complete answer, so if an edge would close a ring while other numbers still need edges, cross it out.

When you try a new tiling, set it to Easy through Custom first. The shapes change how the rules feel, and it helps to get used to the geometry before the hard logic.

Where It Fits

Loopy is a classic for a reason, and the tiling variety keeps it fresh long after square grids feel routine. It suits patient solvers who like visible progress, since the loop grows in front of you. Fans of loop puzzles should also try Pearl Loop Puzzle and Train Track Logic.
