About
Instead of the usual Vegas look, Mason Slots Casino opted for a distinctive theme, drawing inspiration from the secrecy surrounding Freemasonry. The platform operates under a Malta Gaming Authority licence, having launched in 2020 as part of the N1 Interactive Limited family. This company is also behind dozens of other casinos such as Bingo Bonga, CookieCasino, Betamo, Spinia, Bob Casino, and Slot Hunter.
Mason Slots is a sizeable casino with more than 10,000 games from over 120 providers, with a clear focus on slot play. In addition to spinning reels, you can also try out over 150 live dealer tables covering roulette, blackjack, baccarat, and more.
New players can start with a two‑part welcome package that includes a 100% bonus up to €200 plus 50 free spins on the first deposit, followed by a 50% bonus up to €100 and another 50 free spins on the second. On top of that, there are recurring reloads and “secret” free spins offers themed around the Masonic Lodge.

Bonus & Promotions
Mason Slots Casino offers a modest lineup of promotions, but it covers enough to cater to both new and regular players. You can claim a two-part welcome bonus, a weekly reload bonus, free spins, or VIP prizes.
On Wednesday, the casino offers a 25% reload bonus of up to €100, and every Monday, you can redeem 25 free spins from the casino’s secret monthly slot selection.
The bonuses come with a 40x wagering requirement, which is within industry standards. However, all bonuses require that you use codes to unlock them.
The VIP program also features additional bonuses and rewards if you are a recurrent player. If you enjoy competitions, the casino features table and slot progressive prize pools where you can take on other players for the top spot on the leaderboard. 
Welcome Bonus
For your first two deposits, you can redeem a welcome bonus package of up to €300 and 100 free spins. This bonus requires a minimum of at least €20 for every stage, an accessible amount for most players. However, you have to be cautious to put in the ‘welcome’ and ‘key’ codes for each deposit, or else you won’t be able to claim your bonus. The Mason Slots Casino bonus has the following structure:
- 1st deposit: 100% up to €200 + 50 Free Spins
- 2nd deposit: 50% up to €100 + 50 Free Spins
The bonus and free spin winnings have a 40x wagering requirement, which is slightly higher but still attainable. However, the first match bonus has to be wagered within 5 days, while the second deposit has an even shorter term of 3 days. Free spins have a 5-day lifetime for both bonus stages and will be credited in batches of 25 free spins within 24 hours of your deposit.
The maximum bet is €5. The best part is that the welcome bonus does not have a maximum cash-out limit, so you can redeem any extra wins resulting from using this bonus.
VIP Bonus
At Mason Slots, you are enrolled automatically into a VIP scheme after making your first deposit, so you don’t have to wait for an invitation. You earn 1 comp point (CP) for every 1 EUR or USD you wager on slots. Those points move you through a 20‑level Masonic hierarchy, where each rank unlocks a fixed reward.
You can earn free spins on specific slots at the lower tiers, followed by cash rewards and, ultimately, a travel experience to “Masonic places” at the last level.
The early levels feel achievable, as the first few ranks require a few hundred to a few thousand CP and pay out free spins on popular games. Another notable aspect is that both cash and free spins come with a low 3x wagering requirement and are credited within 24 hours. You can even ask support to credit the equivalent cash instead, which adds flexibility.
However, higher ranks demand very large amounts of CP for cash prizes; for instance, you need 1,250,000 CP for a €500 bonus. Realistically, only very dedicated or high‑stakes players are ever going to see those final titles.
Overall, we liked that the VIP program feels transparent and reasonably player‑friendly in the early and mid levels.
Banking & Speed
You can choose from more than 30 payment methods at Mason Slots, including Visa, Mastercard, Trustly, Skrill, Neteller, Neosurf, Paysafecard, Rapid Transfer, standard bank transfers, Bank ID, and others. However, cryptocurrencies are not currently supported.
Deposits and withdrawals both start at €20, which is friendly enough for most casual players, and the cashier was easy to use once we were logged in.
Maximum payout limits are set at €4,000 per day, €10,000 per week, and €40,000 per month, which should be acceptable for mid‑stakes and casual players. However, larger amounts might be paid out in monthly €20,000 instalments if they go over €40,000.
Processing times can take up to three business days, and you will be asked for ID on your first cashout or when total withdrawals pass €2,000, which is standard KYC procedure.
Another drawback is that all deposits must be wagered at least 3x before you can withdraw, which is higher than the single‑turn or 1x rollover many casinos use and can feel restrictive.
Games & Providers
It’s no secret that Mason Slots has a sprawling lobby of over 10,000 titles, although this selection varies depending on your login location. This amazing variety is supported by 121 providers, featuring renowned studios such as NetEnt, Play’n GO, and Hacksaw Gaming.
Here, you can find classics, slots, live games, table games, jackpots and drops and wins. Slots represent the bulk of the lobby at Mason Slots Casino, so you know you can find some of the best RTP slots in the industry here. Some of these popular titles include Starlight Princess Super Scatter, Coins of Zeus, and Wild West Trueways.
From the search filter, you can browse to the Table Game collection and play virtual versions of baccarat, blackjack, poker, and dice. The live casino section is where you can get into real-time gaming, as there are over 150 live tables hosted by professional croupiers. You can play titles such as Lightning Roulette, Dream Catcher, Mega Ball 100x, and Monopoly Big Baller.
Safety & Responsible Gaming
Mason Slots Casino’s operations are regulated by the Malta Gaming Authority, under the license number MGA/B2C/394/2017. As part of the Malta Gaming License, the casino is obliged to provide fair games, and thus all titles come with an RNG certificate that proves all results are fair and random.
For all data transfers, your information is protected with 128‑bit SSL encryption alongside PGP technology, so both logins and payments are protected from third‑party access.
Mason Slots supports playing only for fun, and as such, provides many useful tools and guides for maintaining control. The Responsible Gaming page features practical tools that you can directly access from the “Personal Limits” area of your account. From here, you can set deposit, loss, wager, and session limits, enable reality checks, or activate a cooling‑off break for a set period if you need time away.
If things feel more serious, you can also enable a self‑exclusion, either for a fixed duration or indefinitely. You can also seek additional help by using the links for organisations such as Gamblers Anonymous, Gamcare and Gambling Therapy.
Unfortunately, we have noticed a significant discrepancy in their Trustpilot reviews, as the current review distribution cannot yield an average rating of 4.1 on a 5-star scale. With 66% 1-star reviews, the mean rating would be 2.2/5, not 4.1/5. While this does not automatically mean this would be the actual rating, it is advisable to read a few individual reviews rather than relying only on the headline score.
Support & Design
Mason Slots Casino players can get in touch with the customer support team through email or live chat messages. In our testing, the live chat connected almost instantly, and the agent’s replies were clear and to the point, which made solving small issues feel instant.
There is also a helpful FAQ page that we recommend that you check out before reaching out directly to support.
As you can tell by the name of the casino, the design leans heavily into its Masonic theme, with deep greens, symbols, and secret‑society imagery that gives the lobby a unique personality compared to more generic sites. The navigation is simple and intuitive, with the main tabs listed at the top of the site for easy browsing.
The site runs smoothly and looks sharp, with crisp visuals and quick loading, whether you are on Apple, Android, or Windows devices. There is no dedicated mobile app, but playing through the browser feels almost identical on phone and desktop, with the same features and a responsive layout that resizes nicely on smaller screens.
Conclusion
Mason Slots Casino is a solid pick if you enjoy a wide variety of slots but still want access to classic casino staples. You can bounce between modern video slots, jackpots, and traditional table games, all supplied by well-known software providers.
The site itself is straightforward to use, with an intuitive layout that new players can figure out within a few minutes. The promotions are fairly standard, with a welcome package of up to €300 plus 100 free spins, followed by a couple of reload offers that add some extra value without being over the top. The upside is that the welcome bonus does not come with a maximum cashout cap, which makes it more attractive than many similarly sized offers.
If you are after reliable gameplay, easy navigation, and a themed environment that stands out a bit from the usual casino crowd, Mason Slots delivers a decent experience, especially for slot‑focused players.
