Welcome bonus: four deposits and the exact match at each step
The welcome package is spread across your first four deposits. At its maximum, the package adds up to $6,750 in bonus funds and 250 Free Spins. Each stage has its own promo code, minimum deposit and match percentage, so choose the code that belongs to the deposit you are making.
| Deposit | Promo code | Match | Free Spins | Minimum deposit |
|---|---|---|---|---|
| 1st | FLASH1 | 100% up to $1,500 | 50 FS | $30 |
| 2nd | FLASH2 | 125% up to $1,500 | 100 FS | $30 |
| 3rd | FLASH3 | 75% up to $1,500 | 50 FS | $30 |
| 4th | FLASH4 | 50% up to $2,250 | 50 FS | $30 |
There is also a separate High Roller 1st Deposit Exclusive. It gives 200% plus 100 Free Spins with code WIN200 and needs a minimum deposit of $750. The package terms below still matter, particularly the $5 maximum bet and the 7-day window.
Promo codes: choose the right offer before you deposit
Promo codes connect a deposit with a particular promotion. For a new account, the sign-up form includes a promo-code field. Enter the code for your chosen offer, then make the required deposit in your preferred currency. Your Login gives you access to the cashier and eligible promotions, while bonus conditions apply to the specific offer you select.
- Choose one promotion
Check whether you want a reload, Free Spins, a monthly match, a Lucky Box or the crypto reward.
- Use the matching code
Enter the code in the available promo-code field when registering. Codes such as WINFS and WEEKEND belong to particular days and deposit conditions.
- Meet the deposit rule
Make the minimum qualifying deposit shown for that promotion. The welcome stages require $30, while some other offers use different thresholds.
- Keep the offer terms handy
Wagering, validity, maximum win and bet limits can change between promotions, so use the terms for the bonus you selected rather than assuming every offer works the same way.
| Code | Promotion | Reward | Main condition |
|---|---|---|---|
| 50BONUS | Tuesday Reload | 50% plus 25 FS | Minimum deposit $20 |
| WINFS | Unlimited FS Thursday | 50 FS per qualifying deposit | Minimum deposit $30; 30× wagering; every Thursday |
| WEEKEND | Weekend Free Spins Max | Up to 500 FS | Minimum deposit $30; Saturday and Sunday; up to 5 claims per day |
| 75BONUS | 3rd Deposit Booster | 75% up to $450 | Use the code with the booster offer |
| MONTHLY | Monthly Reload | 75% up to $1,125 | Minimum deposit $30; 50× wagering; 7-day validity; 10× max win |
| BUDDY100 | Buddy Boost Bonus | 100% plus 100 FS | Use the code with the Buddy Boost offer |
| RARE | Lucky Box | One of ten random bonuses | Deposit $40 or more; open up to 3 times per day |
| AlreadyBonus | First-deposit extra | 50% more on the first deposit | Does not conflict with the Welcome Bonus; Welcome Bonus terms apply |
No Deposit Bonus: 20 spins without making a deposit
The No Deposit Bonus gives you 20 Free Spins without a deposit. Each spin is worth $0.50, and the code is Private. It is limited to the first 100 activations, so the offer is aimed at early claims rather than ongoing use.
Use the exact code shown for this offer and keep its Free Spins separate from the four-deposit welcome rewards. A Mobile App is not needed to manage the promotion because the full website is available through a mobile browser.
Free Spins: the games, values and wagering rules
The four welcome Free Spins are assigned to specific BGaming titles. The first-deposit spins are for Elvis Frog in Vegas, the second-deposit spins are for Gold Rush with Johnny Cash, the third-deposit spins are for Wild Cash x9990, and the fourth-deposit spins are for Fruit Million.
| Offer | Free Spins | Game | Wagering | Maximum win |
|---|---|---|---|---|
| 1st deposit | 50 FS | Elvis Frog in Vegas | 40× | $300 |
| 2nd deposit | 100 FS | Gold Rush with Johnny Cash | 40× | $300 |
| 3rd deposit | 50 FS | Wild Cash x9990 | 40× | $300 |
| 4th deposit | 50 FS | Fruit Million | 40× | $300 |
| High Roller first deposit | 100 FS | BGaming Free Spins reward | 40× | $300 |
Every welcome Free Spins reward has a $300 maximum win and must be wagered 40× within 7 days. There are also recurring spin offers: Unlimited FS Thursday provides 50 FS per qualifying deposit with 30× wagering, while Weekend Free Spins Max runs on Saturday and Sunday and permits up to 5 claims each day.
- Weekend Free Spins Max offers up to 500 FS in total.
- The published examples are 40 FS for a $20 deposit, 60 FS for a $50 deposit and 100 FS for a $100 deposit.
- Tuesday Reload adds 25 FS to its 50% deposit match.
- The High Roller first-deposit option includes 100 FS.
The code for Thursday is WINFS, and the weekend code is WEEKEND. The game-specific welcome rewards and the recurring offers have different spin counts, so check which promotion is active before you start playing.
Reloads and cashback: regular ways to add extra value
The welcome package is only one part of the bonus line-up. Mateslots Casino also has reload offers for regular deposits, plus cashback based on certain losses. These promotions are useful when you are not using one of the first four deposit stages.
| Offer | Reward | Code | Terms |
|---|---|---|---|
| Tuesday Reload | 50% plus 25 FS | 50BONUS | Minimum deposit $20 |
| Unlimited Match-Up Weekend Edition | 50% up to $1,500 plus 50 FS | - | Weekend promotion |
| Monthly Reload | 75% up to $1,125 | MONTHLY | Minimum deposit $30; 50× wagering; 7-day validity; 10× max win |
| 3rd Deposit Booster | 75% up to $450 | 75BONUS | Deposit booster offer |
| Buddy Boost Bonus | 100% plus 100 FS | BUDDY100 | Buddy promotion |
| Crypto Bonus | Extra 7% on every crypto deposit | - | No wagering requirement and no limits; credited in account currency |
Cashback works differently from a deposit match. Daily Cashback reaches up to 15% on lost slot bets, while Weekly Cashback pays 10% on live game losses. The crypto bonus is the simplest ongoing reward from a wagering perspective: the extra 7% has no wagering requirement and no limits.
Bonus wagering: the numbers that control your play
The main welcome package requires wagering of 40× the bonus amount. That means the calculation is based on the bonus funds, not the deposit. For example, a $100 first deposit produces a $100 bonus, creating $4,000 in wagering.
- A $1,500 bonus at the first-deposit cap creates $60,000 in wagering at 40×.
- A $750 deposit under the 200% High Roller offer creates a $1,500 bonus, which means $60,000 at 40×.
- A $100 deposit under the Monthly Reload creates a $75 bonus. At 50×, that is $3,750 in wagering, with a maximum win of $750 under the 10× rule.
| Game type | Contribution |
|---|---|
| Slots | 100% |
| Roulette | 5% |
| Blackjack | 5% |
| Video poker | 5% |
| Baccarat | 5% |
| Other card games | 5% |
The maximum bet while a bonus is active is $5 per spin or round. The general maximum win is 10× the bonus amount. Welcome bonuses must be used and wagered within 7 days, and deposits must be wagered at least 3 times before a withdrawal.
VIP and extra promotions: rewards beyond the welcome package
Entry VIP status is assigned upon registration. A total qualifying deposit of $3,750 reaches the VIP threshold, and a personal manager contacts you within 24 hours of reaching it. VIP status can also be transferred from another casino.
VIP benefits include reduced wagering, higher cashback, exclusive bonuses, elevated withdrawal limits, priority service, private events, club gifts and 24/7 VIP support. The next level after ENTRY includes up to 15% slot cashback and 10% live cashback.
- Fortune Drop has a $450,000 prize pool across 8 stages.
- Lucky Spin offers prizes up to $187,500.
- The Referral Program pays $150 per referred friend.
- Lucky Box requires a $40 or larger deposit, allows up to 3 openings per day and gives one of ten random bonuses.
- Lucky Box Sale offers up to $45 off.
- A Bonus Shop and RCP Booster are available.
These extras sit alongside the deposit bonuses and Free Spins rather than replacing them. As always, play for entertainment and set a deposit limit or use self-exclusion if gambling stops feeling comfortable.
