A two player game where the players insert numbers into squares in turn
1. Moves are valid as in Sudoku
2. Moves alternate from Player 1 to Player 2
3. If your move causes an unsolvable board, you lose,
the other player wins
4. If the board is solved, it is a tie
Additional Information:
Clicking "Solve" will display the current board's solution,
but will not end the game! You can "Unsolve" it
"Play for Me" plays the next valid move
which leads to a solvable board
