Sudoku Solver On Device AI

Can Erten

A genuinely novel Puzzle & Game Solvers entry that solves Sudoku with a custom transformer trained on millions of puzzles rather than backtracking, running sub-10ms on the Apple Neural Engine with a correctness-verification layer. Camera OCR input and a fully offline, free model make it a strong showcase pick.
