## What is Sudoku Solver On Device AI?

Sudoku Solver solves Sudoku puzzles using a custom transformer neural network — reasoning through constraints in milliseconds.

WHAT MAKES THIS DIFFERENT

Traditional solvers use brute-force backtracking. Sudoku Solver takes a fundamentally different approach, using an encoder-only transformer trained on millions of puzzles. The model learns the deep structural patterns of the grid to predict solutions in a single forward pass.

HOW IT WORKS

The neural network sees all 81 cells at once and predicts blank cells simultaneously. On-device inference runs in under 10ms on the Apple Neural Engine, providing lightning-fast results with mathematical correctness via a built-in verification layer.

FEATURES
- Solve any 9x9 Sudoku puzzle in milliseconds
- Scan printed puzzles with your camera — Vision OCR detects digits automatically
- Review and correct scanned digits before solving
- Enter puzzles manually with a tap-to-place grid
- See the AI's predictions highlighted vs. the original clues
- Cell-by-cell animated solve reveal
- Input validation highlights conflicting digits as you enter them
- Undo support
- Dark mode
- Runs entirely on-device — no internet required, no data leaves your phone
