BetFred Casino Bonus Question

[Sciolist]

I am dumb.

I am going by a list of casino bonusses, working through them one by one. It includes BetFred as a blackjack bonus. I do the bonus (£3k playthrough), wonder why I don't have the funds credited yet, check the T&C and find that blackjack is no longer counted towards playthrough.

Has anyone done the BetFred bonus by another game? What's worthwhile, and is there a strategy sheet for it? For what it's worth, I was still +£50 during this playthrough. I run good.
