Daily puzzle rules

A fresh set every day at midnight UTC, the same for everyone. Solve any one of them to keep your streak. Each puzzle below takes a minute to learn.

Word Trail

Word · 6–8 min

Guess the hidden five-letter word in six tries.

  • Guess the hidden five-letter word in six tries.
  • Type any real word and press Enter.
  • Green tile — right letter, right spot.
  • Yellow tile — in the word, wrong spot.
  • Grey letter — not in the word at all.
  • Everyone gets the same word; a new one at midnight UTC.

Word Ladder

Word · 7–9 min

Change one letter at a time. Stay a word.

  • Turn the start word into the target word, one letter at a time.
  • Every rung must be a real word — type it and press Enter.
  • Wrong tries cost nothing. Guess freely; the clock is the only score.
  • A locked rung can still be a wrong road — backspace straight back into it.
  • Exactly one shortest chain exists, and you are on its trail.
  • Everyone climbs the same ladder; a new one at midnight UTC.

Balance

Logic · 4–6 min

Balance suns and moons — never three in a row.

  • Fill the 6×6 board with suns and moons.
  • Each row and column gets exactly three of each.
  • Never three of the same symbol side by side.
  • = between two cells means they match; × means they differ.
  • Tap a cell to cycle: blank → sun → moon.

Mini Sudoku

Number · 8–10 min

Fill every row, column, and box with 1–6.

  • Fill the 6×6 grid with the numbers 1–6.
  • Every row must have 1–6 exactly once.
  • Every column must have 1–6 exactly once.
  • Every 2×3 box must have 1–6 exactly once.
  • Tap a cell, then tap a number to fill it.
  • Clashes turn red so you can spot them early.

Mini Sums

Arithmetic · 5–8 min

Fill 1–5 so every cage makes its number.

  • Fill the 5×5 grid with the numbers 1–5, once in every row and column.
  • Each outlined cage must make its number using the sign on its line.
  • A sign sits on the line between two cells of the same cage.
  • A number may repeat inside a cage, but never in a row or column.
  • A few cells are filled for you — the rest is deduction, never guessing.
  • Tap a cell, then tap a number. Notes pencil in what a cell could be.
  • One board a day, the same for everyone; a new one at midnight UTC.
