What about sudoku makes it a good fit for CNNs? Or do you mean the machine vision for converting the pixels into an awareness of the sudoku puzzle's initial conditions?
A relatively simple graph theory algorithm can solve it (and at multiple orders of magnitude fewer calculations). Even a naive brute force search is considered tractable, considering the problem size. Although, search could be considered one of the AI tools in your proposed toolbox.
