Yes, qualifying bets are straight wagers/sportsbook only. I played the $50 and won $45, then made 15 bets of $5 (This is apparently enough to make the rollover requirment - I asked because I thought I had to rollover 15x the $50 in it's trueist sense i.e. 15 bets of $50, support said 15x $5 was ok). I was waiting for my last bet of $5 to be decided before I could attempt the cash in of $25 when I went on roulette and lost about $40. Idiot!

I received the offer in an email.
