1. 1Open the cashierLog in to Mason Slots Casino and open the cashier. Check the casino's terms for how to claim and when the bonus or spins are credited.
2. 2Enter the codeType welcome where the cashier asks for a bonus code. The terms do not confirm the exact field or timing, so ask support if it is unclear.
3. 3Deposit at least 25The minimum deposit is 25. The terms do not list the currency of that amount.
4. 4Check the bonus landsAsk support when the bonus and the 100 free spins are credited, since the terms do not state the timing.
5. 5Read the game listCheck the bonus terms for the game weighting before you play the spins.

Four terms decide this one. The 40x wagering sits above the 30x I see on most welcome offers. The maximum bet is 8 while the bonus is active. The minimum deposit is 25. The terms do not list a maximum cashout or an expiry date.

• Keep every bet at 8 or below while the bonus is active
• The terms do not list an expiry date
• No cap on bonus winnings is stated
• The terms do not say whether 40x applies to the deposit, the bonus or both
• Game restrictions and weighting: The offer is listed as valid for 25 FS on Book of Dead and 25 FS on Rise of Merlin. The terms do not say which games count toward the 40x wagering or at what percentage. Ask support about weighting before you play the spins.
• Country restrictions: Availability varies by location; the casino's terms list the excluded countries.
• Withdrawal limits: The terms do not list a maximum cashout for this bonus. Mason Slots Casino processes cash-outs in 3-5 days, and e-wallets such as Skrill and Neteller are named as the faster routes.
• Excluded payment methods: Deposits can be made by Visa, Mastercard, Skrill, Neteller, Trustly, Paysafecard, Neosurf, Sofort, Zimpler, iDebit, Interac and bank transfer. The terms do not say which of these qualify for the bonus, so confirm with support before you deposit.

The wagering multiplier is 40x. The terms do not say whether that applies to the deposit, the bonus or both, so I cannot price the playthrough for you. The minimum deposit is 25 and the maximum bet while wagering is 8, both bare numbers because the terms do not list their currency. No worked example is available: without the base of the multiplier, any turnover figure would be my guess, not the casino's rule. Screenshot the bonus terms page before you deposit.

I would take this if I planned to play Book of Dead or Rise of Merlin anyway and I was happy to keep bets at 8 or below. I would skip it if I wanted a quick cashout, because 40x is above the 30x I expect and the terms do not say what the multiplier applies to. My main worry is the missing cashout cap: without it, a big win could meet a rule I cannot see yet. Ask support which balance the 40x hits before you deposit. Play within your means and remember 18+.
