Most slot machines run in this fashion utilising simple Fixed Odds Betting. Most (all?) casino table games use the same principle with varying rates of odds. Blackjack with 1 deck is normally the highest payout at about 98% IIRC. Slots hover around 90% and some thing like bingo can go as low as 80% with people still playing happily. There are laws that govern payout percentages (Nevada is something like 75% IIRC). In the UK, slot machines do not always run this way as there are laws in place (recently updated) which require the slot machines to run more like a scratchcard does, with a guaranteed win every X plays, so you could watch people playing and then know that there is a win due soon and step in to play and win :)
