Here in Asia/Taiwan, the claw machines by-law must display the money required to be spent to Win the prize. These are a good example because they are also skill+gambling. All claw machines Trigger a win if X dollars a spent in a certain duration. I suspect these key machines are based on a similar logic. AFAIK Poker Machines in Australia at licensed venues aren't required to display winning odds :/
