Welcome Bonus Terms and Conditions

The 30x wagering requirements must be met within 30 days. Winnings from bonus funds are capped at 5x the bonus amount. Not all games contribute equally to the wagering requirements - slots count 100%, while table games contribute only 10%.

The maximum bet during wagering is €5 per round. Exceeding this limit may result in the forfeiture of bonus and winnings. The bonus must be fully wagered before any withdrawal can be made.

Interwetten Bonus Codes

Currently, no bonus code is required for the welcome bonus at Interwetten Casino. The bonus will be credited automatically after your first deposit. However, codes are occasionally released for special promotions and seasonal offers.

Interwetten regularly informs about new bonus codes via email newsletter and in the customer area. Existing customers can also receive exclusive codes for reload bonuses or free spins. It is worth checking your inbox and the promotions section regularly.

Free Spins Bonus

Interwetten Casino regularly offers free spin promotions for new and existing customers. Currently, there are 50 free spins available for selected slots after your first deposit. The free spins are tied to wagering requirements of 30x.

The free spins usually apply to specific games such as Book of Dead, Starburst, or Gonzo's Quest. Winnings from free spins are subject to the same wagering requirements as the welcome bonus. The maximum win from free spins is often limited to €100.

No Deposit Bonus

Interwetten does not currently offer a classic no-deposit bonus. The best alternative for new players is the 50 free spins after the first deposit of €10 or more. These free spins offer a risk-free opportunity to get to know the casino.

For players who want to start without making their own deposit, Interwetten Casino occasionally holds prize draws with instant wins or free spins. These promotions are announced in the promotions section and via newsletter.

Ongoing Promotions for Existing Customers

Interwetten Casino rewards loyal players with weekly reload bonuses, cashback promotions, and special weekend offers. The reload bonuses typically offer 50% to 100% bonus on deposits with moderate wagering requirements.

Every Monday, there are special slot tournaments with prize money, while on weekends, there are often increased cashback rates or free spin promotions. All current promotions can be viewed in the customer area.

Cashback Offers

Interwetten offers a weekly cashback of up to 20% on net losses. The exact amount depends on the VIP level and is automatically credited every Monday. The cashback is not subject to any wagering requirements and can be withdrawn immediately.

Losses from the Live Casino and slots are considered equally. The cashback is credited as bonus money but is not subject to any further conditions and can be used or withdrawn as desired.

VIP & Loyalty Program

The Interwetten VIP program includes five levels from Bronze to Diamond. Players collect points through betting - a €1 stake earns 1 point on slots and 5 points in the Live Casino. Higher levels offer better cashback rates, personal account managers, and exclusive bonuses.

Diamond members receive up to 20% cashback, higher withdrawal limits, and invitations to exclusive events. VIP status is reviewed monthly and can be maintained or improved with sufficient activity.

Sports Betting Bonuses

Interwetten offers separate sports betting bonuses such as bet credits and accumulator bet bonuses. New sports betting customers often receive a 100% bonus up to €100 on their first bet. The bet credits are subject to their own wagering requirements of typically 5x.

For existing customers, there are regular promotions such as "bet lost, money back" offers or enhanced odds on selected events. The sports betting bonuses are separate from the Casino offers and cannot be combined.

Wagering Requirements Explained

Wagering requirements define how often bonus funds must be wagered before a withdrawal is possible. At Interwetten, the welcome bonus has a 30x requirement - meaning with a 100€ bonus, 3000€ must be wagered. Slots count fully, table games only 10%.

Efficient strategies for meeting the requirements include playing slots with a high payout percentage such as Blood Suckers (98%) or Book of Dead (96.2%). Table games are less suitable due to their low contribution. The maximum bet of 5€ during wagering should be strictly adhered to.
