Sudoku Events — Limited-Time Challenges

Sudoku Events are limited-time challenges with themed puzzles and collectible rewards. Each event brings new puzzles to solve — complete them to unlock beautiful postcard puzzles you can keep forever.

Each event shows you exactly which puzzles are available and how many you've completed. Difficulty is color-coded, and a countdown timer shows how long the event lasts. Don't miss out — once it's gone, it's gone.

Unlocked postcards appear in a carousel below the puzzles. Swipe through them and tap to view the full art. A dot indicator shows how many you've collected. All rewards are completely free — no purchases, no subscriptions.

New events appear throughout the year, each with fresh puzzles and new postcards. Complete them all to build a growing collection of artwork tied to your Sudoku journey.
