Hi Stan,
Is the payout information hard coded or in XML format? With the pick games there are multiple ways to win and EL only calculates one. Pick 4 example:
A straight hit like 9993 is also a 4-way Box win. The check package only counts the straight hit and not the additional 4 way box. I'm pretty sure there are other examples where additional ways to win are not counted.
I have attached an example pick 4 payout schedule.
Thanks
