Promo code types and how they boost your rewards
What Promo Codes Are
A promo code is a short text code you enter in Mars Casino to unlock a specific offer. The offer is tied to that code, so the bonus, free spins, cashback, or a tournament ticket only applies if the code is accepted.
Mars Casino limits promo codes by time, region, and account status. A code can also be restricted to one product, such as slots only, or it can require a minimum deposit amount before it applies.
Where To Find Them
Mars Casino publishes promo codes in three places: email campaigns to registered players, push notifications inside the casino app, and the “Promotions” section in your account menu. The same code can appear in multiple channels, but the terms stay the same.
Some codes are distributed through partner sites and streamers. Those codes often have short expiry windows and a fixed number of redemptions, so they stop working once the limit is reached.
How To Activate A Promo Code
Log in to Mars Casino, open your profile, and go to Bonuses or Promotions. Find the field labeled Promo code, paste the code, and press Apply; the site shows a confirmation message if it is accepted.
If the code requires a deposit, complete the deposit after applying it and use the same payment method allowed by the offer. Check the bonus card for the wagering requirement and the deadline, then start playing the eligible games so the progress meter moves.

Wagering (Playthrough) Terms At Mars Casino
At Mars Casino, a wagering requirement (also called playthrough) is the total amount you must bet before a bonus and any winnings from it can be withdrawn. A 30x requirement on a $50 bonus means you need $1,500 in qualifying bets; stake size, game type, and maximum bet limits decide what counts.
- Example 1 (Slots, 100% contribution): You claim a $100 bonus with a 35x wagering requirement. Required playthrough is $3,500 ($100 × 35). If you place $1 spins on eligible slots that count 100%, you need 3,500 spins at $1 each in total stakes to complete wagering.
- Example 2 (Mixed games, different contributions): You claim a $200 bonus with a 30x wagering requirement, so the target is $6,000. If slots contribute 100% and blackjack contributes 10%, then $2,000 in slot bets counts as $2,000 toward the target, while $2,000 in blackjack bets counts as $200—so mixing in low-contribution games increases the total amount you must wager to reach $6,000.

How do I sign up at Mars Casino from my phone without getting stuck halfway through?
Open the Mars Casino site, tap Sign Up, enter your email and a password, then confirm your email link. You’ll be asked to fill in basic details so the casino can run identity checks before payouts.
Where do I find the Mars Casino login if the homepage keeps changing on mobile?
The Login button sits in the top-right menu on mobile; tap the three-line icon if you don’t see it. If you forgot your password, use “Forgot password” and reset it through the email you used at registration.
Can I deposit with Apple Pay or Google Pay at Mars Casino, and what are the minimum amounts?
Mars Casino supports cards and e-wallets, but Apple Pay and Google Pay depend on your country and the payment provider shown in your cashier. The minimum deposit starts at $10 for most methods, and the cashier shows the exact limit before you confirm.
How long do withdrawals take at Mars Casino, and why does the first one take longer?
Withdrawals take 0–24 hours for internal review, then the payment method adds its own transfer time (cards can take 1–5 business days, e-wallets are usually faster). The first withdrawal can take longer because Mars Casino completes ID and payment ownership checks.
How do bonus terms work at Mars Casino when I’m playing slots, like what does “wagering” actually mean?
Wagering means you must place bets totaling a set multiple of the bonus amount before you can withdraw winnings tied to that bonus. Slots usually count 100% toward wagering, while table games often count less or don’t count at all, and the exact percentages are listed in the bonus rules.
Can I play at Mars Casino for free first, just to test the games before I deposit?
Mars Casino offers demo mode on many slots, so you can spin with play money without depositing. Some games and some providers restrict demo mode depending on your location and device.
Where do I check if a specific game is available at Mars Casino, like a certain slot provider or live dealer table?
Use the search bar in the lobby and filter by provider or category like Slots or Live Casino. If a title doesn’t show up, Mars Casino either doesn’t carry it in your region or the provider has it temporarily disabled.
How do I reach Mars Casino support quickly if I’m locked out or a payment is pending?
Open the Help or Support section and start Live Chat for the fastest response, then share your account email and the transaction ID if it’s about payments. Email support works for document checks, but replies take longer than chat.
