  • 1st deposit offer: 100% up to £25
  • 2nd deposit offer: 50 Extra Spins on Big Bass Bonanza
Bonus Details

Once UK gamblers join Red Casino and make a minimum £20 deposit, they can claim the first deposit promotion.

The offer is valid for 21 days. You can use the bonus on multiple casino games, except video poker, roulette, and others. The maximum bet is set at £4. You can cash out unlimited winnings if you fulfill the 35X bonus rollover.

Pros & Cons

Pros

  • The period of 21 days to use the bonus is extensive
  • The wagering requirements of 35X are decent
  • You can withdraw as much as you win without restrictions

Cons

  • The £20 qualifying deposit is high
  • Not all games are available for this offer.
Bonus Verdict

Red Casino’s welcome package is worth claiming as it offers UK players the chance to play multiple games on the site, including free spins on a popular slot title, with reasonable playthrough. Moreover, the possibility of cashing out everything you win is a great perk. Yet, the qualifying deposit might discourage inexperienced punters.

Promotion Details

Making a minimum £10 first deposit at this casino will grant you a 100% match to it, upwards of £200. The wagering requirements for this bonus are set at 65x. The maximum conversion amount for this bonus is tied to the lifetime deposits, capped at £250. For example, depositing £10 will result in a £10 maximum conversion. The bonus cannot be wagered on table games and progressive jackpots.

Pros & Cons

Pros

  • High value for a bonus that is available only on slots

Cons

  • High wagering requirements of 65x for a first-deposit match bonus
Bonus Verdict

Slots players will find this promotional suitable since the bonus funds are available only on this type. The wagering requirements of 65x must be high for some players, but the maximum cashout is £250 which is a high value for the bonus offered.

You can redeem 100% up to £20 after making your first deposit using the code FIRST20.

Promotional Terms

To be eligible for this promotion, you must make a deposit of at least £10, using the code FIRST20.

The bonus match amount is capped at £20, and it must be wagered 60 times, where only slots contribute to the requirement. The maximum bet you can place is capped at 10% of your initial bonus amount.

Pros and Cons

Pros 

  • Slots contribute fully to the wagering requirement

Cons

  • You can place bets of up to 10% of your initial bonus, which is low considering the fact that the maximum bonus value is capped at £20
  • The 60x wagering is quite high
Bonus Verdict

This promotion is suitable for those who prefer playing with smaller bets, as the bonus value of £20 is quite small. Yet, punters can try out multiple game types with it.

Bonus Details & Redeeming Process

To redeem this BB Casino 100% deposit welcome bonus + the additional spins for Book of Dead, you must be a new customer, and you must trigger the offer via our website’s exclusive link.

This will take you to the exclusive bonus landing page of the casino, where you will find a box called ‘Claim my bonus’. Click it and complete the registration. Furthermore, when you make the £10 minimum deposit, make sure to type the bonus code BB10020; otherwise, you won’t be able to trigger the offer.

Moreover, our team of experts saw that you have only 7 days to complete the 50x wagering requirements. It’s very high, but if you do it, you will be able to withdraw a maximum of 3x the bonus received. 

Pros & Cons

Pros

  • 7 days to clear the wagering
  • £10 min deposit for activation

Cons

  • 50x wagering requirements
Bonus Verdict

Our experts would’ve rated this bonus as perfect, but right now the BB Casino’s 100% deposit welcome bonus is rated as low to mid. Why? Because of the 50x wagering requirements. Still, we liked that you will have enough time to clear the wagering.
