Punters love casino promotions when they’re using their favourite sites, and no type of bonus is more sought after than a no deposit offer.
These offers provide customers with rewards including free spins with no deposit required, meaning users can play a range of popular games without the need to risk their own cash.
Of course, a true casino sign up free spins no deposit bonus will not require a customer to part with any cash, though some offers will provide the chance to gain extra rewards if you do decide to make a deposit.

Who Offers the Best Free Registration Bonus in the UK?
The question of the ‘best’ free registration bonus on the market mainly depends on the individual and what works for them in a betting sense. However, we have our own opinions on the latest offers:
- NetBet: The offer is best for totally free no-deposit sampling, with no temptation to deposit extra for extra free spins as with competing offers. However, the value in the 11 free spins is far lower than competing promos.
- Sky Vegas: This offer provides the best volume in terms of the no wagering free spins, with 50 free spins for no deposit meaning that users have plenty of chances to win without having to risk their own cash. At the same time, the offer for an extra 200 free spins is a huge plus for more serious slot players looking for extra value.
- Betfair: The Betfair promo is the best hybrid promo on offer, with 50 free spins offering good value and the option of an extra 100 for £10 – as well as the lack of restrictions on winnings – providing plenty of opportunity for wins.
