Hello.
I have a 39% bonus but i only receive the base reward. I don't think is normal.
Yes, it is normal. You need to get to 100% to activate the bonus.
How can i do that? I spend all my earnings mostly on lottery and sometimes on multiply from weeks and i barely reached to 39%.
Every time you buy lottery tickets or play multiply the percentage will go up but every time you play a free roll it will steadily go down. Your proportion of purchase has to be greater than your free rolls.
