No payout figure, on purpose. Iowa publishes only the prizes of $50 and up for each game, with how many have been claimed and how many are left. A payout, an expected value or the odds today each need every prize level and how many were printed, so for Iowa we show exactly what its lottery publishes and compute nothing from it. A figure built from part of a table would be wrong, not rough: it is how one state's partial table produced games that appeared to pay back more than they cost. How we treat partial prize tables.
