Determining a slot payout??

I'm going to one of the casino riverboats next friday in Indiana - I am trying to set myself up with the best (losing) odds at winning. I'm having a terrible time finding slot payouts by monetary denomination of slots. I'm looking for the payouts on the .50's and $1.00 slots (argosy, belterra and grand victoria...and possibly the horseshoe in elizabeth). Please help. Indiana gaming commission doesn't have the info!
