Halve the payout each week. So a first week bet on a game is 1:1, 2nd week 1:2, 3rd week 1:4, etc.
Multiple the winnings by the inverse of the percentage of error, i.e., a prediction of 90k for an actual 100k would be a multiplier of .90.
So a person bets $100 on a first week game, predicts 200k, actual number is 210k. Payout is $95. For second week the same amount bet with same number predicted and sold would net $47.50.
With consoles rank bettors and have a staggered payout system based on rank.
I guess you could fiddle around with a lot of different systems.
