You will easily get your money back once you receive your bonus just from the Casino alone by playing slot games. I typically get a 75% overall RTP from the thousands of spins I have played on several different online casinos so I would expect to get back about $45 just from the Casino. So a total profit of $35 from $10 worth of spins. My strategy is to play 20 cent spins on just one game until I either hit a bonus or 10x my wager then move on to a different game playing a maximum of 200 spins, though it may not be possible to play 200 spins using $10, it is entirely possible with the $50 bonus. I'm not very familiar with sports betting but I believe you can bypass Sportsbook and just do the Casino if you'd like, but you would only get the $50 Casino bonus. I would also like to note that this is FanDuel's most current offer according to its Terms & Conditions last update on 10/30/23.
