How Mars Casino free spins work and where to use them

Mars Casino Bonuses Overview

Mars Casino offers a welcome bonus in two parts: a 100% match up to $300 on the first deposit with a 35x wagering requirement, followed by a 50% match up to $200 on the second deposit with a 40x wagering requirement. The minimum deposit for both steps is $20, and the bonus funds expire 7 days after activation. Max bet while clearing the bonus is $5 per spin/hand, and slots contribute 100% while most table games contribute 10% toward wagering.

Free spins come as a separate welcome add-on: 100 free spins on selected slots (for example, Starburst and Book of Dead) credited in two batches of 50 spins after deposits of $20 and $30. Each spin uses a $0.10 stake, winnings convert to bonus funds, and the free-spin winnings have a 35x wagering requirement with a $100 max cashout from that package. Mars Casino also runs weekly promos such as a reload bonus of 25% up to $100 on Fridays with a 35x wagering requirement and promo codes limited to one use per account.

Cashback applies as a loss-back offer: 10% weekly cashback on net losses up to $200, credited every Monday as bonus funds with a 10x wagering requirement and a $5 max bet rule while clearing. Promotions rotate between slot races (for example, a $5,000 prize pool over 7 days with points earned per $10 wagered on eligible slots) and short “happy hour” boosts like +10% extra on deposits from 18:00–20:00 UTC, with exclusions for jackpot and live dealer titles.

First Landing Bonus: 100% up to $200 + 50 Free Spins

Mars Casino credits a 100% match bonus up to $200 on the first deposit and adds 50 Free Spins for Starburst. Free Spins winnings convert to bonus funds.

Midweek Reload: 50% up to $150 (Wed–Thu)

Mars Casino credits a 50% reload bonus up to $150 on one deposit made on Wednesday or Thursday. Bonus funds are added automatically after the deposit.

Weekend Cashback: 10% up to $100

Mars Casino credits 10% cashback on net losses from Friday 00:00 to Sunday 23:59 (UTC). Cashback is paid as withdrawable cash.

1. What Are Promo Codes

A promo code is a short text code that unlocks a specific offer in Mars Casino, such as a deposit bonus, free spins, or cashback. Mars Casino ties each promo code to fixed conditions: eligible games, minimum deposit, and an expiry date. The cashier applies the promo code to the next qualifying payment or to a selected bonus section, depending on the offer type.

2. Where To Find Them

Mars Casino publishes promo codes in its Promotions page and in the account inbox after you log in. Some codes appear in email newsletters if you opted in to marketing messages. Affiliate pages and stream partner posts also share codes, but you still need to confirm the terms on the Mars Casino bonus page before using them.

3. How To Activate

Log in to Mars Casino, open the Cashier, choose Deposit, and enter the promo code in the Promo code field before confirming the payment. If the code is linked to a non-deposit reward, open Bonuses or My offers, paste the code, and press Activate. After activation, check Active bonuses to confirm the bonus balance, wagering requirement, and the expiry timer.

Wagering Requirement (Playthrough) At Mars Casino

The wagering requirement is the number of times you must bet the bonus amount (or bonus + deposit, depending on the bonus terms) before you can withdraw bonus-related winnings. Mars Casino counts only qualifying real-money bets; bets on excluded games and bets that exceed the maximum bet limit do not count.
