Calvin Casino Review

Calvin Casino launched in 2017 and is run by HighWeb Services Limited. It offers an extensive slot range, a live casino and weekend cashback on Red Tiger jackpots.

Calvin operates under a Curaçao licence. It does not accept UK players.

New players get a deposit match with bonus spins. In our records, wagering was 35x the deposit plus bonus, while free spin codes had very high wagering and capped winnings. Current offers are listed on this page.

At weekends, 10% cashback is paid on losses on Red Tiger jackpot slots.

The library includes games from NetEnt, Microgaming, Pragmatic Play, Red Tiger, Playson, Habanero, Endorphina and Kalamba Games, with live games from Evolution and Ezugi.

Methods include Visa, Mastercard, Skrill, Neteller, ecoPayz, Paysafecard, Neosurf and AstroPay. Withdrawals can take up to ten days.

The casino is available on mobile devices.

Live chat is available, but not around the clock; there is no phone support.

Calvin suits jackpot fans in accepted markets outside the UK.

Calvin Casino is licensed in Curaçao, not by the UK Gambling Commission. That means it is not authorised to offer gambling to players in Great Britain, and UK players do not get UK protections such as GAMSTOP, strict affordability checks or the UK’s complaint and dispute rules.

If you live in the UK, choose a UKGC-licensed casino instead – see our best UK casinos. If you live elsewhere, check that online casino play is legal where you are before you sign up.

Signing up at Calvin Casino is quick, but verification usually happens later than at UK-licensed sites:

1. Click Sign up and enter your email, a password, your name, date of birth and address.
2. Choose your currency – including crypto, where available – and enter a bonus code if the offer requires one.
3. Make your first deposit.
4. Before your first withdrawal, expect to upload ID, proof of address and sometimes proof of payment. Doing this early avoids long delays when you want to cash out.

Example: deposit €100 and get €100 bonus. At 35x deposit plus bonus, you need €7,000 of bets.

Offers change regularly, so always check the current terms on the casino site before you deposit.

Casinos without a UK licence are not part of the UK’s GAMSTOP scheme, so the tools available depend on the operator and its regulator. At Calvin Casino, ask support to set deposit limits or to close or self-exclude your account if you need a break. You can also use blocking software on your devices and your bank’s gambling block.

Free, confidential help is available wherever you are – for example Gambling Help Online in Australia (1800 858 858) or the National Gambling Helpline in the UK (0808 8020 133). Read more in our guide to gambling harm.

• Comix – similar Red Tiger cashback.
• ParadiseWin – a sister HighWeb casino.
• VIP Stakes – another HighWeb brand.

Our overall score for Calvin Casino is 4.5 out of 5. It is based on four areas we check for every casino:

We also look at customer support, mobile play and the fairness of terms. Scores are reviewed when casinos change their offers or services.

Withdrawal times are typical ranges after the casino has approved your request, and can vary with verification and your bank. Prepaid vouchers such as Paysafecard usually cannot be used to withdraw, so you will need another method to cash out. Compare methods in our casino payments guide.

Calvin is a decent casino with jackpot cashback. Harsh free spin terms and limited chat hours are the drawbacks, and it is closed to UK players.
