My coworker’s retiring, and we’re throwing a surprise bash at the office. I want it to feel celebratory but not too wild since it’s a workday. Any decor ideas that fit the vibe?

I’ve been thinking about trying Solitaire Clash or Solitaire Cash since I enjoy card games and wouldn’t mind earning a bit on the side. They seem popular, but I’m not sure how they differ or which one’s better for a semi-regular player. Any tips?
