I recently attended a talk by the team that approximately solved the two player head's-up limit hold'em variant of poker. Their strategy is close enough to optimal that a perfectly exploiting opponent would take millions of played hands to expect to extract 1 big blind's worth of value. The Oregon lottery should be held to a qualitatively similar standard. They should state how many cents an optimal player would expect to lose, per hand, by following the default advice instead of playing optimally. Also, there should be regulations about how high that opportunity cost can be. ... not that I think the machines are a good idea in the first place.
