Should we use the fixed numbers and their payout.
are you kidding me? if your system changes the numbers how is that provable fair?
you didn't understand. the payouts are the same in each level. we set the pair of numbers and payouts. so it's changes only after week.. we have 4 pair of each level. after week it's change or stay the same it's random and not our control. we implement that idea so it's looks attractive to the user . they are focusing on the 1 number.
