If you have entered the right total, the circle will continue rotating in a clockwise direction.
If you have made an incorrect entry, you will see the circle reverse direction and start moving in a counter-clockwise direction and you can try entering a different number.
A correct selection makes or continues a clockwise direction movement, while an incorrect entry makes the circle move counter-clockwise. Every time you enter a correct number total, the circling numbers will change and the number you are looking for in the center will change or it may remain the same, but the bottom bar graph will re-start immediately after each correct entry
The red number on the left of the central, circled number indicates the number of incorrect entries, and the green number on the right indicates the number of correct entries..
