MarsBet Welcome Bonus
What’s included: MarsBet offers a 100% match bonus up to $300 on the first deposit, plus 100 free spins. The bonus credits after the deposit is confirmed, and the free spins are issued for a fixed slot: Starburst (NetEnt). The minimum deposit to qualify is $20.
How to claim (step by step): 1) Create a MarsBet account and complete email verification. 2) Open the Cashier and make a deposit of $20 or more. 3) Select the “Welcome Bonus” option before confirming the payment. 4) After the deposit, the match bonus is added to your bonus balance, and the 100 free spins appear in the “Bonuses” section. MarsBet credits the free spins in one batch within 10 minutes of the successful deposit.
Wagering conditions: The match bonus has a 35x wagering requirement on bonus funds. Free spins winnings are credited as bonus money and carry a 35x wagering requirement as well. Slot contributions count at 100%; table games do not count toward wagering.
Time limits: You must use the 100 free spins within 72 hours of receiving them. MarsBet sets a 7-day deadline to meet the wagering requirement; after that, remaining bonus funds and related winnings expire. The maximum cashout from free spins winnings is capped at $100.
What Promo Codes Are
A promo code is a short text code that unlocks a predefined offer in MarsBet, such as a deposit bonus, free spins, or a cashback percentage. MarsBet ties each promo code to fixed conditions: eligible games, minimum deposit, activation window, and wagering rules. A promo code works once per account unless the terms say otherwise.
Where To Find Them
MarsBet publishes promo codes in three places: email newsletters, SMS or push notifications (if you enabled them in your profile), and banner blocks inside the “Promotions” section after login. Some codes are partner-only and appear on affiliate pages or in streamer descriptions; those codes typically have shorter validity periods. MarsBet also sends one-time codes for segmented campaigns, so two players can receive different codes on the same day.
How To Activate
Log in to MarsBet, open the cashier, and choose “Deposit.” Enter the promo code in the “Promo code” field before confirming the payment, then click “Apply” and check that the bonus line appears in the deposit summary. If MarsBet requires manual activation, go to “Promotions,” open the matching offer, press “Activate,” and only then make the deposit tied to that promo code.
After activation, verify the bonus status in the “Bonuses” or “My bonuses” area: it shows the credited amount, wagering target, and expiry timer. If the code is rejected, MarsBet blocks it for a concrete reason: expired date, wrong currency, deposit below minimum, or an account limitation such as duplicate accounts. The fastest fix is to remove the code, re-enter it without spaces, and repeat the deposit flow once.
