01

Generated, not downloaded

Every puzzle is built on your phone from the calendar date, or from openly-licensed data shipped with the app.

02

The same for everyone

One seed per day means your grid is my grid — worth arguing about, worth sharing a result card over.

03

Nothing to sign up for

No account to create, and your puzzles and streaks stay on your device. The only thing that ever leaves is anonymous, opt-out analytics.

Word

Ladders, anagrams and fill-ins built from openly-licensed word lists.

Logic grid

Deduction puzzles with exactly one solution, verified before you ever see them.

Chess tactic

Solver-checked positions with a single winning line — the seed of Daily Tactics.

Strategy

Classics of the genre, reduced to a five-minute daily instance.

Numbers

Arithmetic and placement puzzles generated fresh each morning.

Twenty-one puzzles in all, every day
