This is one of the two sets of buttons you can buy at the Challenge Match table. A $10 donation will get you both sets of buttons, along with a $10 raffle prize ticket and a Daily Drawing ticket. The raffle prizes are amazing, including a Cleveland Cinemas Season Pass, a night at the Ritz-Carlton, a wine collection, and many more! There's a complete list at the Challenge Match table, and some even more spectacular prizes you can get with higher-level donations. But you really don't want to leave without your button set! (I plan to collect them all!)
