In Unibet there is no 5€ UO ticket though
If i remember correctly then with UO tickets there were 2 options to reach main event:
1€-4€-25€-250€-1100€
2€-10€-50€-250€-1100€
Also while playing these satellites there is usually possibility that one ITM-place is giving some cash aswell but this is only when tournament itself have (more than) enough participants ...
