To change or set your betting limits, go to My Account and select the Responsible Gaming section.
Enter the amount you want to be able to bet per week, and select Submit. Then you need to confirm the new limits.
An example: if you set your wager limit at 50 EUR, you place a bet of 25 EUR and another bet of 20 EUR, trying to place a bet of 10 EUR within seven days of placing the first bet will result in your 10 EUR bet being declined.
You can always lower your limits, but if you wish to increase them, that will only take effect 7 days after you placed your increase request.
