I looked at books with bonus from your list. I've just read betOWI bonus conditions. Do I understand correctly that it has
32x rollover?

(On a $500 deposit with a $1,000 bonus and $200 winnings, the rollover requirement is $19,000 ($500 deposit + $1000 bonus = $1,500
x 32 = $48,000)...)
32x rollover requirement is absurd. I like Jetwin 5x and Anonibet up to 10% rebate. After that I like Cloudbet. I wish Cloudbet would go to rollover instead of loyalty points. It seems to take a lot of action to have the bonus released and is somewhat confusing. Then there's a bonus at BetVIP 10x deposit + bonus.
