Hi Edward, Can you chance the collor on the calculators for betting 2 or more units. For example: betting 2 units is Yellow, 3 units orange, 4 light red, 5 units dark red etc.. so you can see in one glimps how many units to place on the doubles and the tripples, now it is not verry clear how many you have to bet on a double or tripple. It looks very much the same. Especialy people with glasses or people who can not distunguise the darker blues... If you get what i mean.
I hope you can work something out.
Thanks in advance!
