Mason Slots Bonus
Registration
New and returning players visit Mason Slots for straightforward offers, clear rules, and quick claiming steps. If you prefer simplicity to guesswork, the headline Mason Slots bonus sets the tone: transparent amounts, visible codes, and practical limits.
From a value perspective, the starter package is straightforward, and the weekly cadence makes budgeting easy. The trade‑offs are modest—one active offer at a time and occasional payment‑method exclusions—but the promos are clear enough that experienced and casual players can plan around them.
This guide compiles every currently advertised deal in one place—welcome steps, weekly treats, codes, and the small print that matters. Use it as a checklist before you deposit and as a reference when planning your next claim.

Mason Slots Bonus Codes
Keep these at hand before you pay—enter them on the promo card and click Add to attach them to your deposit.
These are the current Mason Slots bonus codes:
- WELCOME – First Deposit Bonus
- KEY – Second Deposit Bonus
- WEDNESDAY – Mid-Week Reload
- MONDAY – Secret Free Spins
Codes are case‑sensitive, time‑limited, and sometimes region‑specific. If you forgot to add one, ping live chat right away; retro‑crediting is not guaranteed once funds hit the account. Treat all of these as Mason Slots promo codes and always double‑check the active card before you confirm payment.
RegistrationVIP Programme
Mason Slots runs a tiered loyalty track called Achievements. You’re enrolled automatically after your first deposit and move through 20 ranks by wagering on slots. Each bet earns Comp Points (CPs) that push you to the next badge and unlock a prize.
- How you earn: CPs accrue from slot stakes (posted rate on the site: 1 CP per €1 / $1 / ~CA$1.5 / NZ$2 in bets). Larger volumes naturally move you faster through the ladder.
- What you get: Early ranks award free spins (e.g., 10, 20, 40, 50 FS tiers), while higher ranks unlock cash rewards (advertised examples include €2,500, €5,000, and €10,000) and a top‑tier travel experience at the final badge.
- Credit & wagering: Rewards are typically credited within 24 hours of reaching a level. Both cash prizes and free‑spin winnings carry a 3× wagering requirement before withdrawal.
No Deposit Bonus
A permanent Mason Slots no deposit bonus does not appear on the promo pages. However, short‑term freebies sometimes show up as tournament rewards, inbox surprises, or targeted emails.
If you prioritise zero‑deposit offers, enable marketing messages in your profile, check the promo lobby on Mondays and Wednesdays, and ask live chat whether any opt‑in trials are running right now.
RegistrationMason Slots Bonus Terms & Conditions
Always open the individual promo card and skim the general bonus page—those two sources overrule anything you’ve read elsewhere.
The essentials:
- Eligibility & minimums: Welcome steps and weekly deals usually require a deposit of at least €20. Some payment types may be excluded from a specific card.
- Wagering: Bonus funds and free‑spin winnings carry wagering—check the multiplier on the card. Finish wagering before claiming a new deal.
- Maximum bet while wagering: A per‑spin/hand cap applies (commonly posted on the card); exceeding it may void progress.
- Game contribution: Most slots count 100%; table/live games and high‑volatility features often contribute less or are excluded. Avoid bonus‑buy features unless the card explicitly permits them.
- Spin delivery and expiry: First‑deposit spins arrive in two batches (25 + 25); second‑deposit spins are valid for roughly 3 days. Unused spins expire.
- One offer at a time: Do not stack deals; keep a clean wallet until a bonus settles.
- Verification: Complete KYC early to prevent payout delays and protect any bonus you’ve claimed.
Reading the card takes under a minute and eliminates the most common pitfalls—wrong code, wrong method, or missed minimum.
Frequently Asked Questions
How do I claim the welcome package correctly?
Sign up, verify your email, open the “Promotions” page, and claim the first step with the code ‘WELCOME’ before depositing €20 or more. After wagering or completing the first step, claim the second with the code ‘KEY’ and deposit again.
Can weekly deals overlap with the welcome offer?
No. Only one promotion can be active at a time. Finish the current offer (or cancel it in your profile) before using a weekly reload or spin deal.
My bonus or spins didn’t show—what went wrong?
The usual causes are a missing or misspelt code, an ineligible payment method, or not meeting the minimum deposit. Check your transaction, re‑read the promo card, and contact live chat; agents can confirm status and help fix simple errors.
