Loopy Loop Puzzle
In Loopy Loop Puzzle, your job is to connect a lattice of dots into one big ring. A number in a cell is the count of that cell's edges the ring runs along. Empty cells give no clue at all.
The rules stay the same on squares, triangles, hexagons and even tilings that never repeat, so there is a lot of variety. It loads directly in a browser tab with nothing to install.
How to play Loopy Loop Puzzle
Every possible edge begins yellow, meaning not yet decided. Click an edge to make it black and part of the ring. Right-click to cross it off, which makes it fade. Clicking an edge again sets it back to yellow.
Your finished ring has to be one connected path that never branches, crosses itself or breaks into separate pieces. Clue cells need their count matched precisely. The board flashes once you have it right.
The default board is a 10x10 square grid at Easy. The Type menu lists square grids at several difficulties plus many other tilings. Custom pairs any grid type with Easy, Normal, Tricky or Hard.

Tips
- A 0 cell uses none of its sides. Cross out all of them first, and the surrounding dots often become easy.
- Every dot on the ring has exactly two black edges. Once a dot has two, cross out the rest; if it has one black edge and only one open edge left, that open edge must be black.
- On square grids, a 3 in a board corner must use both outside edges.
- Two 3 cells side by side on a square grid always share their middle edge and both outer edges parallel to it.
- Be careful not to close a small ring early. A closed shape is only correct if it is the entire answer.

Questions
How do you solve Loopy Loop Puzzle?
Draw a single closed path along the grid edges so that every number matches the count of its sides on the path. Work from strong clues like 0s and corner 3s, crossing out edges you know are empty.
What grid shapes does Loopy Loop Puzzle have?
Besides squares, there are triangles, hexagons and several mixed tilings, including Penrose and other non-repeating patterns. All are listed in the Type menu and in Custom.
Can I play it on a touchscreen?
Yes. Tap an edge to draw it and hold it to cross it out. The menu bar with Undo and Solve works with taps as well.
