The Solution

The Solution window lets you watch as the program solves the puzzle for you:

• You can run an animation, with adjustable speed, as the program methodically tries various arrangements of the digits.
• You can single step, both forward and backward, to examine the process in greater detail at you own pace.
• You can skip straight to the solutions. The computer still performs the same calculations in exactly the same way, but without showing any of the intermediate steps. This happens so quickly that it will seem instantaneous.

Notes

• You can adjust the animation speed at any time, whether it is running or not.
• Pause the animation to use the "Single Step", "Skip to Solution", and "Start Over" buttons.
• When the animation is paused, you can click cells to select them. If "Show Info" is checked, you will see information about the selected cell.
• It is not possible to modify values in the cells in this panel. Go back to the Challenge window to experiment.
