MasonSlots runs a straightforward welcome package for new accounts: a 100% match up to $200 on the first deposit, plus 100 free spins on the featured slot of the week. The match requires a $20 minimum deposit, and the bonus funds carry a 35x wagering requirement; free spins winnings are capped at $100 and must be wagered 30x before withdrawal. The welcome offer stays available for 7 days after registration.
For ongoing play, MasonSlots lists a weekly cashback promo that returns 10% of net losses from Monday to Sunday, credited every Monday, with a $10 minimum cashback and a $200 weekly cap; cashback is paid as bonus credit with a 5x wagering requirement. The promotions page also rotates deposit deals such as 50% up to $150 on weekends and slot races with a $1,000 prize pool; most promo bonuses require using the code shown in the promo tile and completing wagering within 72 hours of claiming.
MasonSlots credits a match bonus on your first deposit and adds 50 free spins on a selected slot. The bonus and spins appear within 10 minutes after the deposit is confirmed.
MasonSlots applies this reload bonus on one deposit made between Friday 00:00 and Sunday 23:59 (UTC). The bonus is limited to one claim per weekend.
MasonSlots returns 10% of net losses from Tuesday to Thursday as bonus funds. MasonSlots calculates net losses as stakes minus winnings over the period, after completed bets settle.
A promo code in MasonSlots is a short text code you enter to unlock a defined offer, such as a deposit bonus, free spins on a specific slot, or a cashback deal. Each code has fixed conditions: an expiry date, a minimum deposit, eligible games, and a wagering requirement. MasonSlots applies the offer only after the code is accepted and the qualifying action (for example, a deposit) is completed.
MasonSlots publishes promo codes in three places: the Promotions page in your account, email campaigns sent to subscribed players, and time-limited banners shown after login. Some codes are tied to specific events, like a weekend reload, and disappear once they expire. If a code isn’t visible in your account, it usually means it’s not available for your region, currency, or account status.
Log in, open Cashier, and choose your payment method. Before confirming the payment, find the Promo code field, type the code exactly as shown (letters and numbers), then press Apply to validate it. Complete the deposit that matches the minimum amount; MasonSlots credits the bonus or free spins to your balance right after the payment clears.
After activation, open My bonuses (or the bonus section in your profile) to see the wagering requirement and the games that count. If the code is rejected, the common reasons are: expired code, deposit below the minimum, code already used, or the offer restricted to specific games. Fix the condition and re-enter the same code during a new deposit attempt.

Tap “Sign Up,” enter your email, create a password, and confirm your email link. After that, complete your profile details so deposits and withdrawals don’t get held for verification later.
Use the search bar for a specific title, or filter by category like slots, live casino, or table games. Your recently played list also pulls up past games fast from the lobby.
MasonSlots labels supported titles with a demo option, and you can start those without a deposit. Live casino tables run in real-money mode only.
Deposits support bank cards and selected e-wallets, and they credit to your balance instantly after approval. If a deposit is declined, the cashier page shows the reason and you can retry with a different method.
MasonSlots processes withdrawals after account verification, and payouts follow the payment method’s timing. E-wallet withdrawals clear faster than bank card payouts once the request is approved.
Enter the bonus code (if required) in the cashier or promotions page before you deposit, then check the bonus terms for the wagering number and any game restrictions. If you start playing excluded games, the bonus funds can stop contributing toward wagering.
Open Account Settings and set deposit limits or a time-out period, and the change applies to your account right away. For a longer stop, you can trigger self-exclusion from the same menu.
