About the game
A browser adaptation by Zarocer.
Draw one closed loop around the grid. Number clues tell you how many surrounding edges belong to the loop.
Controls
Click or tap an edge to cycle its mark; use the keyboard to focus edges. Z undoes, H gives a native hint and P opens the native pause menu.
Join the clue counts into one loop
A 0 excludes every edge around its cell. A 3 uses three of the four surrounding edges, but the unused edge still depends on neighboring constraints. At a dot on the loop, exactly two incident edges meet; one leaves an unfinished end and three makes an illegal branch.
Do not close a small loop while other required segments remain outside it. A board can satisfy nearby number clues and still fail the single-loop rule. Use excluded-edge marks to keep track of paths you have ruled out, then inspect the complete route before checking.
Save and continue
ZAROCER opens this build in English. Saved progress and records stay in this browser when storage is available. Use the native continuation controls after reloading. Clearing site data can remove saves. The portal’s Pause, Theater and Fullscreen controls preserve one game instance.
