Best casino welcome bonus offers ranked and reviewed

Online casinos occasionally offer no-deposit bonuses where you are not required to make any deposit to claim the bonus. We like these offers as you simply have to sign up to receive your welcome bonus. As the name suggests, free spins allow you to play online slots without risking your own cash. Each spin is assigned a fixed monetary value, typically ranging from 5p to 20p. Keep in mind that casinos usually restrict these spins to pre-selected titles, with blockbuster games like Big Bass Bonanza or Starburst being common favorites. The beauty of these percentage offers is that you are rewarded on how much you deposit.
