## What is Sudoku?

Sudoku Pure Edition is the last Sudoku app you'll ever need.

500 hand-crafted puzzles across 5 difficulty levels - Easy, Medium, Hard, Expert, and Extreme. Built for beginners who want to learn and veterans who want to be challenged. No filler. No ads. No subscription. Ever.


THE PROGRESSION SYSTEM

Most Sudoku apps end when the puzzle does. Ours is just getting started.

Earn up to 250 badges across 10 categories - Milestone, Difficulty, Perfection, Speed, Streak, Mastery, Daily, Technique, Dedication, and hidden surprises. Early badges come quickly. The rarest ones will take months to earn.

Complete all 500 puzzles to reach Mastery Level 1, unlocking a brand new set of 500 puzzles. Your records and history carry forward. The journey never ends.


BADGES THAT LIVE IN THE REAL WORLD

Play on Earth Day and earn the Earth Day badge. Play on World Lion Day and earn the Pride of Solvers badge. Complete a puzzle on your birthday and earn a personal birthday badge repeated every year with a number marking how many times you've earned it.

Over 67 personal and holiday badges refresh annually. There's almost always something to play for.
