Sudoku Puzzle Pack

A clean, focused Sudoku experience — no accounts, no internet required, no ads interrupting your game.

Two Modes
Classic Sudoku for sharp, logical thinking. Killer Sudoku for an extra layer of challenge, where caged cells add up to unlock the solution. Both modes include 80 handcrafted puzzles across four difficulty levels: Easy, Medium, Hard, and Expert.

Play Your Way
Choose your puzzle from the full grid or let the app pick one at random. Pick up where you left off — your game saves automatically, even across app restarts.

Track Your Progress
Earn up to 3 stars per puzzle. Beat your best time. Review your stats by difficulty and mode to see how you're improving.

Smart Tools

Notes mode for penciling in possibilities
Auto-fill notes to clear candidates as you solve
Hints when you're stuck — highlight mode or auto-fill
Undo, erase, and strike tracking for challenge runs
Play Offline
No connection needed. Every puzzle is built into the app — open it on a plane, in a waiting room, anywhere.

Unobtrusive Ads
A small banner ad sits at the bottom of the screen. No pop-ups, no full-screen interruptions, no ads between puzzles.
