Loop The Loop: Slitherlink

One loop. Every clue satisfied. No guessing required. Loop the Loop is a beautifully clean take on Slitherlink, the classic Japanese logic puzzle. Tap the edges between dots to draw a single continuous closed loop — every numbered cell tells you exactly how many of its four sides belong to it. Solve by pure deduction, never by luck. A NEW PUZZLE EVERY DAY The Daily Loop is the same for every player, everywhere. Come back each day, keep your streak alive, and see how fast you crack it. ENDLESS LEVELS THAT GROW WITH YOU Start small and easy, then climb through infinite procedurally generated levels. Grids get bigger, deductions get deeper, and the difficulty curve is graded — never a wall, never a bore. BUILT FOR THINKING, NOT TAPPING • Tap an edge to cycle: line → X → empty • Mark X on edges you've ruled out, exactly like on paper • Auto Check validates as you play, or turn it off for a pure solve • Timer, pause and reset always in reach • Submit to see your accuracy, your time, and your loop compared to the correct one QUIET AND SATISFYING Smooth line animations, gentle haptics, and a calm interface designed to stay out of the way. Every puzzle has exactly one solution, and it's always reachable with logic alone. PLAY ANYWHERE Fully offline. No account, no sign-up, no internet needed. Your progress and best times are saved on device. If you like Sudoku, Nonogram, Picross, Kakuro or Nurikabe, Slitherlink is your next obsession. Draw the loop.
