Read full descriptionHide full description
Asterleaf is a calm paper-style logic puzzle for iPhone. Each day you solve one compact 6x6 symbol grid using handwritten-style clue notes, careful elimination, candidate marks, and confirmed answers. Every row and column must contain each of the six symbols exactly once. Start with direct clues, mark possible symbols when you are unsure, then confirm the answer when the logic is clear. The Check button helps you spot unfinished cells or conflicts without turning the game into guesswork. Today's puzzle is free. Past daily puzzles and future Pro puzzle packs unlock through the one-time Asterleaf Pro purchase, with restore purchase support through the App Store. Asterleaf has no account system, no ads, no analytics SDK, and no developer backend. Puzzle progress, tutorial state, streaks, and Pro status are stored locally on your device. 服务条款 https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ 隐私政策 https://asterleaf.portrays.app/privacy

The clearest difference is iOS requirement: Deduce at 13.0 against Asterleaf's 17.0. On price, ads, in-app purchases and device support there is nothing between them.
