Title 01 — Closed testing

Foldout

Twenty-one puzzles a day, and everyone gets the same ones. Words, numbers, logic, chess and strategy. It all runs on your phone, so it works on a plane.

01

Made on your phone

The calendar date is the only input. Word lists, quotes and pixel art ship inside the app.

02

The same for everyone

One seed per day: your grid is my grid. Arguing about it is half the point.

03

Nothing to sign up for

No account to create, and your puzzles and streaks stay on your device. The only things that leave are anonymous crash reports and usage stats, and one switch in Settings turns them off.

Word

Ladders, anagram hunts and ciphers, built from openly-licensed word lists and public-domain text.

Logic grid

Fill the picture from the clues, or bridge the islands. Both are proven solvable before they ship.

Chess tactic

Solver-checked positions with one winning line. Daily Tactics grew out of this shelf.

Strategy

Reversi, peg solitaire and sliding-block puzzles, cut down to five minutes.

Numbers

Sudoku, cage sums, Latin squares and shade-the-duplicates.

Twenty-one puzzles in all, every day
