Sudoku webapp. Just for fun (done at Makers). Ruby and Sinatra. Features a neat recursive solver, and a generator guaranteed to generate puzzles with a unique solution.

Part of the initial solver implementation was done pair-programming with Bruce Steedman.

Install deps with bundle install, run with rackup, test with rspec.
