This is a set of solvers for sudoku-like games. Since the motive for this program is making an experiment in the efficiency of brute-forcing the solution, there is no fancy GUI. All input/output is text-based. And indeed, the brute-force method has shown to be very efficient. Most puzzles are solved in under a second, some hard ones (that some people took 6 hours to solve!) taking up to 2 minutes on 2GHz Pentium M.
The archive includes solvers for sudoku, killer-sudoku and kakuro.
