Single-Clicking on the arrows under the digits reverses the sequence of the digits from the first digit to the "clicked" digit. By continued reversals, you can make the random digits progress from 1 to 9. When you have accomplished this Herculean feat, then you have won the game.
Correct sub-sequences are shown as Light Green or Dark Green , and correct, but reversed (high to low), sub-sequences are shown as Light Red or Dark Red. Digits that are not part of a sequence, but are in the correct location are shown as Aqua. Out-of-sequence and incorrect location digits are shown as Black.
