BGO GIANT
I am ready for WITCHES BREW BONUS
Oooh hold up:
I'm afraid you will use your Real Funds (Deposit) first, as Halloween Fortune is what is classed on-site as an "Excluded Game", meaning it doesn't contribute to wagering whatsoever, meaning it doesn't take Bonus Funds.
As a general rule, Bonus funds will be placed first if you have any previous pending winnings from the same associated bonus. If not, then your real balance will be taken if again associated with same bonus. If you have neither real funds or any pending winnings, the bonus amount itself will be used. Any winnings will be used to top up the original bonus amount and initial real cash deposit associated with the bonus. If you have no bonus associated then naturally real funds will always be taken.
Lotto Madness is a VF game, who are the same people that provide the Bingo on-site. If you're playing with a Casino bonus, you won't be able to play any VF games, as it'll take the real funds first.
