➰ Slitherlink
Connect dots into a single closed loop: each number says how many of its four sides carry a line, the loop never branches or crosses itself. Puzzles come from a real generated loop and are pruned to a unique solution.
How to play — Slitherlink
Draw lines between neighbouring dots to form ONE single closed loop — it never branches, never crosses itself, and has no loose ends.
Each number counts how many of the four edges around that cell belong to the loop (0–3). Cells without numbers are free.
Tap between two dots: 1st tap = line · 2nd = ✕ “no line” note · 3rd = clear. Starters: every edge of a 0 gets ✕; a 3 next to a 0 forces its three other edges; two 3s side-by-side share a line plus both outer edges.
Tap between two dots to draw a line; tap again for ✕ (no line), a third tap clears. A number turns red when overloaded and dims when satisfied. Corners are your friends: 0 means no lines at all, a 3 in a corner forces both outer edges.
