OrderInsight

Solve compact number grids at your own pace with an offline experience built for focused play. The app includes 6 x 6 and 9 x 9 puzzle sets organized into chapters, plus a daily challenge selected from the verified local catalog. Resume an unfinished game, choose a specific level, or open the guide to learn the rules with a small interactive practice board. Gameplay supports direct number entry, candidate notes, undo, check, pause, restart, and up to three hints per puzzle. Hints explain a verifiable deduction so you can keep learning while you play. Incorrect entries are marked through conflicts rather than by revealing the answer. Progress is stored locally on the device. Track completed puzzles, best times, total hints, and undo usage in the statistics view. Customize the experience with light, dark, or system theme modes and optional helper display. The app works offline and does not require an account, cloud sync, ads, or social features. Your local saves and preferences remain on the device.
