Is the Mason Slots Casino Bonus Worth It?

The welcome bonus offers decent value for most players when compared to Ireland's best casino promotions.

The playing period could be longer but the remaining conditions make it a fine offer. 

You get credit for playing 90% of Mason's games and there's no cap on the amount you can win.

Key Benefits:

✔️ Unlimited Potential - 100 spins allow you to play for unlimited prize money on two hot slots

✔️ Fair Playthrough - a 40x playthrough sits just within acceptable standards.

Who is this Bonus Best For?

✔️ Both deposit offers suit all users and the wagering requirements won't push you too hard

The promo team at Mason Slots Casino puts its faith in reload bonuses with two weekly offers. 

You get 25 free spins and up to €100 in site credit when you use the deposit bonus codes MONDAY and WEDNESDAY, respectively.

A VIP program runs alongside weekly reload bonuses. 

There are 20 tiers, ranging from Treasurer to Honourable Master and each one contains free spins or up to €10,000 in bonus cash. 

Reach the top rank and you'll be jetting off to exotic locations that have links to "Masonic" lore.

Mason Slots Casino accepts EUR deposits from €20. 

There are 10 legit payment methods to choose from, including debit cards, Skrill and Neteller. 

You can also make direct deposits using Mandato and Rapid Transfer.

Withdrawals start at €20 and transactions are processed instantly via all available methods, including Skrill, Neteller, MiFinity and Paysafecard's eWallet. 

There are also three bank transfer methods. 

Rapid Transfers start at €50, while standard transfers and PayAnyBank have minimums of €100.

Only verified users can withdraw funds from their accounts. Fortunately, completing the process is easy. 

Just go to the profile menu and select "Documents". 

There, you'll see three boxes: Identity, Address and Payment.

Drop screenshots of your ID, proof of address and payment method into each box. 

Finally, verify your phone number (using the SMS code) if you haven't already. 

The security reviews KYC documents daily, so your account will be verified within 24 hours in most cases.

There were over 10,000 games to choose from at the time of publishing this Mason Slots Casino review. 

Stacks of Top Slots

This online casino lives up to its name by working with leading software providers from around the world. 

Big brands like NetEnt and Pragmatic Play are supported by a cast of equally creative niche names, such as RetroGaming.

Diversity gives all customers a chance to find slot games they enjoy, which is important. 

Beyond being able to play everything from classics to Megaways slots, diversity breeds individuality. 

Indeed, it's rare but refreshing to see thematic slots like Mascot Gaming's Riot alongside mainstream hits such as Sugar Rush 1000.

All Types of Jackpot Slots

Overall, Mason Slots' website is well put together. However, there's a slight issue with the jackpot slots lobby. It houses over 1,900 games, so that's the official figure. 

But, on closer inspection, most of the games have fixed jackpots.

The issue is that games with multiple fixed jackpots, like Book of Captain Silver, are listed alongside those with progressive payouts, such as Amusnet's Genius of Leonardo. 

So, if you're only interested in progressive jackpots, the actual number of games you can play is closer to 100.

Hundreds of Live Casino Tables

Mason Slots Casino offers a small selection of RNG table games, including blackjack, roulette and sic bo. While that would normally be a problem, it's not in this case because there are 700+ live dealer games.

The gaming team's strategy appears to be brute force because the sheer number of options is almost overwhelming. There aren't many surprises in terms of the games you can play. 

If action is your thing, there are hundreds of blackjack, roulette and baccarat tables, as well as 45 game shows, including Playtech's Greatest Cards Show and Evolution Gaming's Monopoly Live.
