It's very accurate at knowing the answer will always be 9,18,27,36,45,54,63,72,or 81 , so it always has the same symbol on these numbers, all the rest is the foil :cheesy: :cheesy:
...I did think along those lines but I had different icons coming up all the time....for example I thought of 92, 57, 91....and all those answers are with differnt icons....
