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.
