I was the only one without a target to hit but it was my responsibility to engage with people and get their thoughts on the game, the bets, and who was willing to dish out some coin.
Muggleborns and muggle-raised were pretty much hooked since UNO was a fan favorite and anything resembling muggle entertainment was welcome. Magicalborns had more reservations but this (very public) game showed there were no hidden tricks (that they could see). The biggest draw however had to be the purebloods.
They followed the game more intensely than anyone and had questions upon questions about what other kinds of games muggles had. Yeah, they'd seen other non-magical card games but nothing with so many twists and turns.
Oh yeah, we had these people hooked. Hermione will be very happy to drain these poor people dry.
