What it does
Sudoku-solving agent developed in the classroom lectures to solve diagonal Sudoku puzzles and implement a new constraint strategy called "naked twins". A diagonal Sudoku puzzle is identical to traditional Sudoku puzzles with the added constraint that the boxes on the two main diagonals of the board must also contain the digits 1-9 in each cell (just like the rows, columns, and 3x3 blocks). The naked twins strategy says that if you have two or more unallocated boxes in a unit and there are only two digits that can go in those two boxes, then those two digits can be eliminated from the possible assignments of all other boxes in the same unit.
How we built it
The pygame library is required to visualize your solution -- however, the pygame module can be troublesome to install and configure. It should be installed by default with the AIND conda environment
