This calculator requires the use of Javascript enabled and capable browsers. This is a game of thinking. The objective is to line up the letters in alphabetical order beginning with A and ending with O. The blank space goes in the last position. Click on the letter adjacent to the blank space that you want to move. The letter you clicked and the blank space will reverse positions. The box at the bottom of the board displays the number of moves. You may restart the same game with a fresh counter or you may start an entirely new board by clicking on the appropriate button. Enjoy.
