Daybook 益智 应用 为 Android 描述
Daybook
Daybook is a daily logic-puzzle app for people who like to think.
Every day brings a fresh set of classic logic puzzles: Sudoku, region and placement puzzles, number, sign and symbol grids, pipe networks, flood-fills, one-line paths, code-breaking and chess mate-in-N puzzles. Each comes in three difficulties, Standard, Hard and Expert, and each is built so that it has exactly one answer you can reach by reasoning. Nothing needs guessing.
NO ADS. NO SUBSCRIPTION. NO ACCOUNT.
There are no adverts, no paywall, no sign-in and no in-app purchases. The app does not even ask for network access, so it works on a plane, on a train and in a tunnel.
THE WHOLE ARCHIVE, FROM DAY ONE
Puzzles are made on your device from the date, so every past day is already there. Missed a week? Play it. Want something different? Switch to Random boards at any difficulty.
LEARN AS YOU GO
Stuck? Ask for a hint and Daybook explains the next step in plain language, pointing at the cells it is talking about, rather than just filling one in. Every puzzle has a short walkthrough for first-timers, and How to play is always one tap away.
KEEP YOUR STREAK
Track your daily streak, your times and your statistics, all stored privately on your phone.
PRIVATE BY DESIGN
Daybook collects nothing. No analytics, no trackers, no third-party SDKs. Your progress never leaves your device.
Hand-built puzzle generators, proven boards and a calm, uncluttered design. Come back tomorrow for the next one.
