oddschecker looked at the most popular free spins offers for existing customers to find out how do they work, how many free spins they offer, and what games you can use them on.
The easiest way to get a casino bonus is to open an account on a new website and claim their welcome bonus. What many players don't know is that there is a good number of UK casinos that offer free spins to their existing customers as well.
Here on oddschecker, we bring you a list of the best free spins offers for existing players available in June and July 2021 - with potentially more than 1,000 free spins up for grabs to play the top slot games out there.
1. EnergyCasino: Deposit £10, Get 50 No-Wager Spins
The first (and probably the juiciest, too) free spins offer for exiting players is the one you find at Energy Casino, where a £10 deposit buys you 50 spins on Book of Dead with no wagering requirements.
Energy Casino is not new to no wagering free spins, and the promotion available right now is probably your best chance to discover the iconic video slot by Play n'Go.
To claim this bonus, you need an account at Energy Casino (you can get one here) and a deposit of £10. After that, opt-in for the promotion and the 50 free spins are yours.
While there are no wagering requirements applied to this free spins offer for existing players, the wins are capped at £100. The free spins appear on your account immediately after the opt-in and expire seven days after crediting.

To access this bonus, existing customers need to opt in and bet £10 on any of the online slots included in the site's collection. As soon as this simple two-step process is completed, the 5 casino free spins are credited into the player's account.

As we explain in our Sky Casino review, this site offers also a £60 bonus to all new customers who deposit and wager £10 on their site, so it's probably a good time to join and have a look at their games.

There are daily bonuses for existing customers at 888casino too, as the sister site of the second-largest online poker room in the world continues to promote their exclusive Wheel of Fortune.

4. All British Casino: Marvellous Midweek and SuperSpins
All British Casino is another great place to score a little something extra. As the name of this promotion suggests, the site rewards all the existing players that choose to play between Tuesdays and Thursdays with a different offer every week.
The weekly bonus comes mostly as free spins for existing players, although there have been weeks when we have seen deposit match bonuses of £10 or more.
The best ones so far have been the offer that rewarded every depositor 40 free spins on Rainbow Riches Megaways and the one that distributed the site's SuperSpins for free.
All you need to claim the weekly bonus is to opt in for marketing materials and bonus offers and make a deposit of £10 or more between Tuesday and Thursday. The casino sends also reminders of their Marvellous Midweek promo via email, so it's nearly impossible for All British Casino customers to miss it.
