What’s inside.

Over a thousand puzzles

Easy, Medium, Hard and Expert. Start gently and move up when you feel like it.

Free hints, always

A hint fills in one square correctly. You never watch anything, and you never buy anything.

Pencil notes

Jot down the possibilities in a square, just like you would on paper.

Large, clear numerals

Numbers sized to be read at arm's length without reaching for glasses.

Leave a puzzle half-finished

It saves automatically. Come back to it whenever you want.

Light or dark

Choose whichever is easier on your eyes, or let it follow your phone.

Made to be comfortable.

  • Large numerals and touch targets
  • Clear notes without clutter
  • No timer on by default
  • Works with no internet
