Answer
Greetings;
The answer depends on other T&C. Losing BJ you lose a game with an EV of less than -.5% for most software. The alternatives have to be less than -3% or you will really play with fire! If allowed Craps, Roulette (single zero or en prison rules), Baccarat(banke & player), Sic Bo (large or small bets only), Pai Gow, Casino War and Three Card Poker(pair plus) are all under that negative EV. The latter four are not present at all software providors however. And the first three, usually are not allowed for wagering requirements.
But the real bottom line is unless this bonus is extremely generous, I would avoid the casino entirely. There are way too many reputable casinos that allow BJ or even better, BJ Switch, towards your wagering requirements.
Bon Chance!
