Tip 1: Check the bonus percentage and maximum amount
It is important to check the bonus percentage and maximum bonus amount. Most casinos give a 100% bonus on your first deposit. But some casinos reach 150% and even 200%. In some casinos, the maximum amount is also very different, from € 50 or € 100 to even € 200 to € 300. If you take into account both factors, you can easily decide what is the optimal first deposit.
If the bonus percentage is 100% and the maximum bonus is EUR 151, do not deposit more than EUR 151. You will then receive € 151 + € 151 = € 302 on your first deposit. If you deposit less, you will also receive less bonus. So you get a € 50 bonus if you deposit € 50 and play a total of € 100.
