Arrow Loop vs Teach the Thief

Sharpen your logic in quiet focus. One loop. A few shaded cells. That's the whole rule — and the longer you look at the board, the clearer your mind becomes. Use the arrow-and-number clues to shade exactly as many cells as each arrow points to, then draw a single closed loop through every remaining cell. Shaded cells never touch side by side, and clue cells are never shaded or crossed by the loop. WHAT YOU GET - A pencil logic puzzle in the Yajilin style: draw the loop, shade the cells - Every board has exactly one answer - Hand-picked boards you can solve by reasoning alone. No guessing required - Four levels from Easy (6x6) to Expert (12x12), graded by the depth of reasoning - Today's puzzle: one board for everyone, set by the date - Drag to draw the loop, tap to shade a cell - Leave a puzzle and continue right where you stopped - Ranks and titles that grow as you solve - Gentle help when you're stuck: mistake highlighting and hints - Six board themes: Indigo, Ink, Vermilion, Pine, Sakura and Night - Fully offline. No sign-up - English and Japanese, in a calm paper-and-ink style MADE FOR YOU IF - You want to turn a few spare minutes into quiet, focused thinking - You enjoy Slitherlink, Nurikabe, Sudoku or nonograms - You're tired of ambiguous puzzles and ad-heavy apps - You love the satisfying click of a single, certain answer - You'd like a small bedtime ritual with nothing chasing you PEACE OF MIND - Free to start.

Pick two treasures that share a color, a shape, or both, then watch Pip scoop up everything that matches. The trick? Make every grab count—and leave the protected treasure alone. A LITTLE CHOICE.
