The bonus offer of Interwetten works is that you do not get the bonus immediately after the deposit, but in five steps.
Something unusual, but actually very customer friendly this 100% 100 EUR bonus!

In addition, one still gets a 10 € free voucher, so to deposit coupon code SUPER BONUS enter and the 10 € will be credited immediately.

How the Interwetten Bonus:

Subscribe here at Interwetten and equal pay (within 10 days of registering) to your newly opened Interwetten account (min. 10 EUR).

Within 14 days after registration you have had more time "freizuwetten" the bonus.
Once you (with odds 1.70) in the total value of your deposit (eg 100 euros) have set betting, you get 20% of it as a bonus (not the subject to further conditions).
After the next sales in the amount of the deposit, you get the next 20% as a bonus, etc. until you get 100% bonus.

So, to get the maximum bonus of € 100 it works like this:
Deposit 100 € betting › › 20 › 100 EUR Euro Bonus Bet 20 Euro Bonus › › › 100 Euro Bets Bonus 20 € 100 € betting › › 20 › 100 EUR Euro Bonus Bet 20 Euro Bonus ›

And do not forget - in addition there is the € 10 bet token that is credited immediately. So a total of 110 € bonus.
