Keep in mind, though, that on many games, you’ll be making more than just one wager on one payline. Using that logic, dollar slots are perfect for players who are bored by quarter slots but who can’t afford the $5 slots. The rule of thumb, when playing slot machines, is to play for as high a denomination as you can afford, because the higher denomination machines offer a higher payout percentage than the lower denomination machines. Dollar slots are slot machine games which cost a minimum of a dollar to play.
