Logic Trio

Three logic puzzles a day, printed like a poster: one yellow, one blue, one red. Solve them over coffee and watch your times come down.

Everyone gets the same three puzzles each day. Each has exactly one solution and never needs a guess. There are no ads and no account.

THE THREE STRIPES

Crowns
Place one crown in every row, every column and every colored region. Crowns never touch, not even at the corners. A star battle puzzle.

Binary
Fill the grid with suns and moons. Never three in a row, and every line holds as many suns as moons. The = and × tags tell you which neighbors match. For binairo and takuzu fans.

Path
Draw one line from 1 through every cell, meeting the numbers in order. It looks easy until you notice the corner you skipped.

HINTS THAT TEACH

Tap Hint and the board hatches the cells to look at. Tap again and it tells you why, in plain words, then makes the move. A few days later you'll see those steps on your own.

PROOFS, BACK ISSUES, TALLY

Proofs are endless practice puzzles in four levels, from Easy to Expert. Back issues keep every past Daily on a calendar. The Tally counts your solves, records and runs.

YOUR DAY RUN

Solve a Daily and your run grows. Miss a day and a freeze covers it, one a week. Your run sits on the Lock Screen, today's stripes on the Home Screen, and a spoiler-free result is one tap away when you finish. With iCloud on, saved puzzles and your run move between your devices.
