I don't have any free bets as of right now for this up coming week. They tightened up their free bets promotion and offered it on roulette instead of blackjack, so I decided to pass on their promotion. Blackjack has about .5% house edge while roulette has about 5.26% house edge.

So here is the $100 free bet on roulette promotion. Play $1,000 on roulette and get a $100 free bet. At 5.26% house edge you will on average lose $52.60 on $1,000 play. The free bet is only worth around $90, and assuming you only win half of you free bets the free bet is only worth $45. So you are out $7.60. Does everyone agree with my calculation? You can parlay to get over $100 on you free bets, but they don't win as often. Anyway to make this promotion positive expected value?
