About Clear Skies Logic
Clear Skies Logic is a small, free logic-puzzle ritual: every day there is a new Binary puzzle (easy 6×6 and harder 8×8) and a small Kakuro. Everyone in the world gets the same puzzles on the same day, and new ones arrive at midnight New York time.
Fair puzzles, every time
Each puzzle is checked by computer before it is published to make sure it has exactly one solution. You never need to guess. Careful reasoning always gets you there.
Made for everyone
- No account, no sign-up, no paywall.
- A large print & high contrast mode (the “Aa” button), full keyboard control, and screen-reader labels.
- A print button for people who prefer pencil and paper, with the answers on a separate page.
- Your streaks and statistics stay on your own device.
Who makes it
The puzzles are made by Nolan Fairweather, who creates logic-puzzle books and printable puzzle packs. If you enjoy the daily puzzle and want more to work through at your own pace, see the Nolan Fairweather Printables store or the books on Amazon.
