Tic Tac Toe Solitaire
DON'T GET THREE IN A ROW!
Click the small X or O within the cell to set it. Click again to clear it. Use up all five Xs and Os in each column and row. You can not set any three consecutive cells in a column or row the same. Diagonals don't count. These are hard logic puzzles much like Sudoku. If you win just click the [Solved!] button to play again. If you get stuck the green flag will give you a different puzzle every time. Enjoy!
Jan 23, 2016 Update: Click the Recycle symbol to reset current puzzle. Fixed Solved button glitch. Added wait statements to forever loops to save CPU time.
