Sloterra Casino No Deposit Bonus – Get 30 free spins on Zeus the Thunderer ✔ Active

No-deposit rewards upon registration are rare nowadays, but we have an exclusive special treat for our readers. New players joining Sloterra Casino will grab 30 free spins on Zeus the Thunderer slot. These free spins will enable you to test the casino and its games without committing a real money deposit. The best part is that you can wager this bonus and convert it into withdrawable cash. However, to do that, some conditions must be met. For instance, to grab the 30 FS, you must use a unique free spins code, BBCASINOS30. Also, you must wager the free spins winnings 35x before requesting any cashout from this reward.

For example, if you win €30 from the free spins bonus, you must wager this amount 35x. Therefore, you must rollover €1050 (30*35) to withdraw any winnings. Notably, maximum winnings from these FS are capped at €50, and you must first deposit funds to your account to withdraw winnings from this no-deposit bonus. Also, the max bet while wagering is €10, and bets above this limit will not count towards meeting the wagering requirements. The free spins bonus is only available for 7 days. So, it would be best if you were quick to use it.

  1. Go to Sloterra Casino
  2. Sign in to your account.
  3. Tap the “Deposit” button, select your preferred payment method, and enter your deposit amount, from €10 to €50, depending on your bonus stage.
  4. Select the bonus you’d like to claim, First deposit bonus, Second deposit bonus, etc., from the available options.
  5. Click “Deposit to complete.”
  6. Now go to the bonuses section, and under the “My bonuses” panel, click “Active.”
  7. If you made a qualifying deposit, the bonus will appear in this “Active” section. Now, tap “Activate Bonus” to claim it.

How to wager your welcome bonus

Wagering your signup bonus can be herculean, even with a low wagering requirement. Still, it’s manageable, but you’ll need lady luck by your side. Sloterra’s welcome bonus has a 35x playthrough requirement. This is a relatively fair wagering requirement compared to others that require you to roll over the reward 50 or 60 times.

So, how do you wager the online casino’s welcome bonus? Suppose you deposit €10 to claim the first 100% up to €200 welcome deposit bonus. In that case, you’ll receive €10 as your bonus, meaning you’ll have €20 as your total bankroll. As such, since you’re wagering only the bonus amount 35x, you must wager at least €350 (35*10) to request payouts from bonus winnings. However, please note that your real money balance is used up first while playing with a bonus. The max bet while wagering the welcome bonus is €10, and the reward is valid for one week.

Sloterra Casino’s welcome bonus terms and conditions

  • The reward is available for new players, except for gamblers in Sweden.
  • You must activate the bonus to use it.

Regular promotions and bonuses in Sloterra Casino

New and existing gamblers can use other bonuses besides the welcome bonus and no-deposit free spins running all week. For instance, every Monday, under the Lost Treasure bonus, you can grab a 30% match bonus by depositing at least €50. This reward will be credited automatically without using any deposit bonus codes. Besides that, if you’re a slot lover, you can grab 100 free spins each day in the Trouvaille promotion. To claim these spins, you must deposit a min of €60 and use the spins on Zeus the Thunderer slot. Interestingly, this promotion doesn’t have a maximum cap on bonus winnings.


Crypto enthusiasts aren’t forgotten at Sloterra Casino. Hence, if you’re depositing via cryptocurrencies like Bitcoin, you can get a 50% bonus of up to 0.02 BTC or 20 mBTC in the Tomb Raider promotion. This bonus is available once every week, and you must deposit a minimum of 0.002 BTC or 2 mBTC to claim it. Moreover, slot fanatics can claim 55 free spins daily on The Tomb slot with the Sand & Gold promotion. You don’t need a casino code to claim these FS, but you must deposit at least €20 to claim them. Winnings from this free spins promotion are capped at €50.

Finally, players can enjoy a mythical-themed adventure every Sunday with a 25% match bonus plus 25 free spins on The Myth slot by Mascot Gaming. This Shady Enterprise promotion doesn’t require you to redeem any casino bonus codes, but you must deposit at least €30 to claim it. Notably, this bonus doesn’t come with restrictions on maximum bonus winnings. All these regular bonuses must be wagered 35x, activated from the bonuses section, and adhere to the €10 or 0.0003 BTC max bet limits while wagering.

Sloterra Casino Weekly Cashback – Up to 17%  ✔ Active


Casino Sloterra offers players a weekly cashback program, but it’s tied to the casino’s VIP club. As such, the cashback is available to players who’ve achieved the second VIP level onwards. Your deposits and real money losses in the last week must be greater than €500 to qualify for this bonus. However, players playing with cryptocurrencies aren’t eligible for cashback. Cashback is awarded every Wednesday, and the cashback percentage will depend on your loyalty level as follows:

  • Level 2: 5%
  • Level 3: 7%
  • Level 4: 9%
  • Level 5: 11%
  • Level 6: 13%
  • Level 7: 15%
  • Level 8: 17%


Please note that cashback will be calculated from bets made from real money only- bonus wagers don’t count. Once cashback is awarded, players from levels 2 through 6 must wager the bonus 3x, while gamblers in levels 7 and 8 will receive wager-free cashback bonuses. Players must wager the awarded cashback bonus within 7 days or risk losing the reward. This is the formula for calculating cashback in Sloterra Casino: (total bet amount – winning amount) x (loyalty level cashback percentage).

Sloterra Casino VIP program

This Bitcoin online casino rewards players with an 8-stage loyalty club and points program. Once you register, you automatically join the casino’s VIP club, but the more you deposit and play, the higher you’ll rise through the VIP ladder. You must accumulate the required experience points to progress through the loyalty tiers. Therefore, for every €20 or mBTC 1 you deposit, you’re awarded one experience point. Here’s what Sloterra’s VIP club structure looks like:

  • Level 1: 0-500 points.
  • Level 2: 501-1000 points.
  • Level 3: 1001-2500 points.

  • Level 5: 5001-10,000 points.
  • Level 6: 10,001- 20,000 points.
  • Level 7: 20,001- 30,000 points.
  • Level 8: 30,000 + points.


Each time you advance to a new level, you’ll receive rewards. Some of the prizes include free chips, surprise rewards, bonus money, free spins, and of course, cashback, with lower or zero wagering requirements. Sloterra Casino has a dedicated tournament section, but there are no ongoing competitions. We reckon they’ll be added in the future.

In this modern era, mobile phones have become powerful devices capable of performing a wide range of tasks, including online gambling. Fortunately, Sloterra Casino recognises this and offers a seamless mobile casino experience.

The mobile casino loads quickly and provides a diverse selection of real-money online casino games optimised for mobile play. Moreover, players can enjoy the same range of services and features, including the availability of various payment methods, bonuses, and customer support options, just like its desktop counterpart.

Security, fairness, and licencing

Sloterra Casino is a safe and secure online casino site with a Curacao e-Gaming Authority licence. This licence assures that the online casino adheres to strict regulations regarding game safety, responsible gambling, and player fairness.

The maximum deposit threshold will depend on your payment option, but all deposits are processed instantly and carry no charges from the casino’s side. Nevertheless, your payment provider may sometimes charge you some transaction fees. Regarding withdrawals, the least you can cash out is €20, and the online casino can conduct KYC verification on your first withdrawal at the site at its discretion.

You must provide legal documents like ID, passport, driver’s licence, and a utility bill to verify your identity.

The online casino has daily, weekly, and monthly withdrawal limits of €5000, €10,000, and €30,000, respectively, but if your winnings are 10 times larger than the total of your lifetime deposits, you’ll be restricted to a €10,000 monthly cashout limit.
