Why don't you read the T&C's?
I will save you the bother - NO blackjack allowed in WR.
The general T&C lists no BJ, but they also write:
"Where use of the Bonus System is in place for the promotion, the terms and conditions around the Bonus System will prevail."
The bonus system T&C says:
"The contributing percentages are as follows:
1. Slots, American Roulette and Parlor Games count 100% towards wagering requirements
2. Table Poker, all Roulettes excluding American Roulette, Casino War and Sicbo count 50% towards wagering requirements
3. Video Poker, all Blackjacks except Classic Blackjack, Craps and Baccarat count 10% towards wagering requirements
4. Classic Blackjack counts 2% towards wagering requirements"
I understand this to mean the wagering requirements listed above prevail for the sign on bonus. I only played BJ and French Roulette and had no issues. I would not recommend BJ to meet wagering requirements, as it only counts 10%.
