About this game
Logic Atlas is a logic-puzzle atlas built for people who want to actually get better at solving — not just fill grids by luck. Sudoku is the flagship. Bridges (Hashi) is the second region. Each has its own campaign, daily chart, and Quick Play.
SUDOKU CAMPAIGN
Work through a guided campaign that teaches real Sudoku techniques step by step, from Naked Singles and Hidden Singles through X-Wing, Swordfish, Jellyfish, Remote Pairs, and more. Each technique has a walkthrough, then easier and harder practice boards that need that move, so you build genuine solving skill instead of guessing.
BRIDGES CAMPAIGN
Learn Hashi the same way. Six techniques across three chapters — Harbor, Straits, and Archipelago — covering remaining-count fills, isolation traps, closed groups, and must-connect. Walkthrough, then easier and harder charts, with replay whenever you want more practice.
DAILY PUZZLES
A new Sudoku every day and a new Bridges chart every day, the same for every player. Come back to keep each streak going.
QUICK PLAY
Jump in without the campaign. Sudoku on 4×4, 6×6, and 9×9 from relaxed to expert. Bridges on 7×7 and 10×10. Optional hints when you get stuck. Points are awarded for Quick Play (and Daily) completions, not campaign practice.
TRACK YOUR PROGRESS
Stats, streaks, and achievements follow your solving history and celebrate milestones as your skills improve.
DESIGNED FOR EVERYONE
Full dark mode
A low-stimulation visual mode that swaps bright colors for a calmer, muted palette
Clean, distraction-free boards
PRIVATE BY DESIGN
No account or sign-in required. Your progress is stored only on your device — nothing is uploaded, collected, or sold.

Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.
What’s new
Fixed various bugs relating to Plots and the Trophy system.
Daily puzzles now generate on your device a day in advance. This requires the app is running and not generating a quick play board. Daily Puzzles will remain in local storage for as long as you can do a catch-up (one week memory) and the board has not been played, and generates the next days board if all other dailies have been caught up.
This does not guarantee the loading screen will never appear, but significantly reduces frequency.
