Arrow Loop
Read full descriptionHide full description
Sharpen your logic in quiet focus. One loop. A few shaded cells. That's the whole rule โ 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. No subscriptions - No third-party ads - Your records stay on your device (no account needed) - The app shows small cards introducing other apps by the developer (TORANKIRITE). To build them, the app reads public App Store information; nothing about you is sent
Curio Shelf
Read full descriptionHide full description
Arrange each item. Read every clue. Bring the whole cabinet into harmony. Curio Shelf is a cozy spatial-logic puzzle set inside a quiet countryside garden shop. Place a collection of curious objects on a compact shelf, then rearrange them until every item's clue is satisfied. SOLVE 25 CAREFULLY CRAFTED CABINETS Each cabinet adds new items and new ways to think about space. Keep a seed jar beside the fern, separate things that should not touch, find the right row or corner, and work out which object belongs above, below, left, or right of another. EVERY MOVE IS AN EXPERIMENT Drag an item straight onto the shelf, or tap to select and place it. Invalid arrangements are allowed and clearly explained, so you can test an idea, move things around, undo for free, or restart whenever you like. There are no timers, lives, or penalties for taking your time. EARN THREE STAMPS Complete every cabinet, then refine your solution. Place each item efficiently to earn up to three stamps. If you want a nudge, an optional rewarded hint can reveal one correct item placement without finishing the whole puzzle for you. UNLOCK ENDLESS SHELF Finish all 25 cabinets to open an ever-changing mode filled with newly generated arrangements. Every Endless Shelf puzzle is checked for a valid solution before you play. A SMALL SHOP TO SETTLE INTO - Enjoy hand-painted garden-shop scenes, gentle motion, cozy sounds, and responsive haptics - Save your best stamps and settings on your device - Play the core game offline; an internet connection is used for ads - Adjust music, sound effects, haptics, and reduced motion - Play in English, German, Spanish, French, Italian, Brazilian Portuguese, Russian, Japanese, Korean, or Simplified Chinese Curio Shelf is free and contains ads. Optional rewarded ads can reveal a hint. No account or sign-in is required. Every item has its place.

Verdict
The clearest difference is in-app purchases: Curio Shelf at none against Arrow Loop's 1. Curio Shelf also leads on iOS requirement (15.0 vs 17.0). Arrow Loop's advantage is ads (none vs shown). On price and device support there is nothing between them.
