I've never chased a multiplier contest, has anyone ever won a multiplier contest? does this also apply to buy freespin feature or not? Will the bonus be sent immediately after winning the contest?
You can try with bonus buy, but do you think you can meet the target multiplier with bonus buy since multiplier is counted based on how much win divided by how much your bet is.
Lets say you do a bonus buy $20 (base bet for this buy is $0.2) and you won the max multiplier (lets say 5,000x from the base bet = $1000) means that your multiplier is $1000/$20= 50x If you do normal bets/spins and you win the same amount $1000, your multiplier is 5,000x
Now lets see at the target multiplier for the challenges, most of them are above 500x and there is no way for you to win it by bonus buy unless the max multiplier in the game is at least 100,000x ,why?
Simply because bonus buy usually cost you 100x from the base bet so if the max multiplier is 100,000x then you can get max 1,000x as the multiplier.
