Yes, you absolutely can. All you need is a calculator.
Then you calculate your deposit x wager, for example x 35.
For example, if your deposit is €50 x 35 = 1.750 wager amount.
Occasionally, the wagering requirement is based on the deposited amount and the granted bonus.
In this case, you must calculate deposit + bonus x wager.
For example, if your deposit is €50 you must calculate 50 + 50 x 35 = 3.500.
