Mateslots Casino Bonuses: Welcome Offers and Promo Codes

The main welcome package reaches up to $6,750 plus 250 free spins across four deposits. Each deposit has its own percentage, maximum bonus and minimum deposit. There is also a separate high roller first-deposit option for players making a larger opening deposit.

The welcome bonus uses 40× wagering on the bonus amount. Your maximum bet while wagering is $5, bonus winnings are capped at 10× the bonus amount, and you have seven days to use the bonus and finish the wagering.

How the 40× calculation works

Say you make the $30 minimum first deposit and receive a $30 bonus. The wagering target is $1,200, calculated as $30 × 40. The $5 maximum bet still applies, while the 10× cap gives a maximum bonus win of $300 in this example.

For the high roller option, a $750 deposit produces a $1,500 bonus at 200%. The 40× target would therefore be $60,000, and the 10× bonus cap would be $15,000. These examples show why the percentage, bonus cap and wagering number all matter together.

A promo code connects a particular offer to your account. Mateslots gives each major promotion its own code, so check the spelling before entering it in the available promo-code field. Here is the full code map.

The AlreadyBonus offer does not conflict with the Welcome Bonus and uses the Welcome Bonus terms. For the four deposit offers, use the code that matches the deposit number rather than choosing a code at random.

Once you have used the welcome options, Mateslots has several repeat-deposit promotions. They cover weekly, weekend and monthly activity, with different match percentages, free-spin amounts and wagering terms.

Weekend Free Spins Max includes these deposit examples: $20 gives 40 free spins, $50 gives 60 free spins and $100 gives 100 free spins. The reward can be claimed up to five times per day on Saturday and Sunday.

Cashback works differently from a deposit match. Daily Cashback returns up to 15% on lost slot bets, while Weekly Cashback returns 10% on live-game losses.

Other promotions include Fortune Drop, which has a $450,000 prize pool across eight stages, and Lucky Spin, with prizes reaching $187,500. A referral pays $150 for each referred friend who completes registration and deposits. Lucky Box requires a $40+ deposit, can be opened up to three times per day and gives one of ten random bonuses; its sale offers up to $45 off.

1. Pick one offer

   Choose the welcome deposit, no-deposit spins, reload, free-spin or crypto option that suits the way you plan to play.

2. Use the matching code

   Enter the exact code connected to that offer, such as FLASH1 for the first welcome deposit or WINFS for Thursday free spins.

3. Meet the deposit condition

   Check the offer's minimum before depositing. Welcome deposits start at $30, the High Roller option starts at $750 and the no-deposit spins do not require a deposit.

4. Keep the important limits visible

   For the welcome package, that means 40× wagering on the bonus amount, a $5 maximum bet, a 10× bonus win cap and seven days to finish.

5. Track game contribution

   Slots contribute 100% towards wagering. Roulette, blackjack, video poker, baccarat and other card games contribute 5%, so the same cash stake can move the target at very different speeds.

6. Check the balance before a Withdrawal

   Deposits must be wagered at least three times before a withdrawal is permitted. Your Login also gives access to eligible promotions and the full game lobby.

A quick contribution example: a $1 slot bet contributes $1 to the wagering target, while a $1 roulette bet contributes $0.05. If your target is $1,200 and you played roulette only, you would need $24,000 in roulette stakes to contribute that full amount.
