Sudoku Blueprint - Offline

SudokuBlueprint is a clean, focused sudoku puzzle game built around a simple idea: every puzzle should feel freshly made, not pulled from a repeated pool.

ENDLESS, NEVER-REPEATING PUZZLES
Every puzzle is generated on the spot from a random seed, then verified to have exactly one solution. With billions of possible starting grids, you'll never solve the same puzzle twice by chance.

CHALLENGE A FRIEND WITH A CODE
Every puzzle has a 6-digit code. Enter the same code as a friend to get the exact same grid, and see who solves it faster — or use it to return to a puzzle you started earlier.

DESIGNED TO HELP YOU FOCUS
- Pencil-mark notes for tracking candidate numbers
- Undo, erase, and up to 3 hints per puzzle
- A locked-in cell once you've entered the correct number, so you always know what's confirmed
- An original ambient soundtrack composed to support quiet concentration — turn it off anytime
- A minimal, distraction-free "blueprint" visual style

FOUR DIFFICULTIES, FAIR PROGRESSION
Easy and Medium are free to play, each with a small set of fixed puzzles. Solve your way up: beat Medium enough times to unlock Hard, and Hard enough times to unlock Expert. A single one-time purchase unlocks Hard and Expert immediately, removes the puzzle limit on Easy and Medium, and removes ads — no subscriptions, no recurring charges.

BUILT FOR IPHONE AND IPAD
A responsive layout that adapts to any screen size and orientation, from iPhone SE to iPad Pro.

Available in English, Arabic, Chinese(Simplified), Hebrew, Hindi, Indonessian, Japanese, Korean, Malay, Portuguese(Brazil), Russian, Spanish, Thai, Turkish, Vietnamese
