What's inside

Everything Sudoku does. Nothing it pretends to.

  • 01

    Four difficulties

    Easy, Medium, Hard and Expert, each with its own statistics and best times.

  • 02

    Daily Challenge in three tiers

    A fresh Easy, Medium and Hard every day. Complete all three for a Perfect Day, and earn streak freezes for the days life gets in the way.

  • 03

    Hints that teach

    Hint, Auto-Fill notes and Smart Eliminate show the move and the reason, not only the digit.

  • 04

    26 themes

    Soft Mist, Zen Garden, Morning Dew and more. Twelve VIP themes carry animated backdrops and their own number typefaces.

  • 05

    Smart light and dark

    Themes can follow your phone's setting, so a late session goes dark on its own.

  • 06

    Statistics that mean something

    Win rate, average time, streaks and best times, split by difficulty and by daily challenge.
