Mason Slots Casino Review

Mason Slots launched in 2019 and is run by N1 Interactive Ltd, the operator behind N1 Casino and SlotWolf. It offers games from more than 40 studios and personalised bonuses for VIPs.

Mason Slots is licensed by the Malta Gaming Authority. It is not licensed in the UK.

New players get a welcome package. Current offers are listed on this page.

VIP players receive personalised deposit bonuses and other perks.

The library includes games from NetEnt, Microgaming, Playtech, Pragmatic Play, Play’n GO, Nolimit City, Push Gaming, Red Tiger, Yggdrasil and Thunderkick, with live games from Evolution.

Methods include Visa, Mastercard, Maestro, Skrill, Neteller, ecoPayz, Trustly, Paysafecard, Neosurf, InstaDebit and iDebit. Withdrawals arrive within 24 hours once processed.

There is no app; the browser version works on phones and tablets.

Live chat is open 24/7.

Mason Slots suits slot fans in accepted markets who want an MGA-licensed casino with a big library.

Mason Slots is licensed in Malta, 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 Mason Slots 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Example: a €100 bonus at 40x requires €4,000 of bets before bonus winnings can be withdrawn.

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 Mason Slots, 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.

Our overall score for Mason Slots is 4.7 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.
