A simple solver for the Str8ts puzzle. It only works for 9x9 board size.
It uses backtracking without any optimizations, there are no strategies implemented. Just enter the numbers and press the solve button, it will find a solution if there is one. Usually it takes a few seconds for normal puzzles, but the more complex it gets, the slower the program works.
It's a small hobby project that I may improve sometime in the future, but don't expect too much.
