Answer:
No.
Step-by-step explanation:
Technically when an individual enters into a casino and decides to play on of the games in the casino (such as the slot machines) they enter into an agreement with the casino stating that they agree to all losses and profits that may arise from using the machines. Unfortunately, being banned from the casino is also a form of contract which states that if the individual is prohibited from entering the casino or using any of its machines, and also nullifies any winnings gained from the casino's services (such as the slot machines). Therefore in this scenario, there is no contract between the casino and Blackford that supports his claim.
