What's a good iOS game to play where you can actually win some real cash, not just bragging rights?

Okay, so I've been messing around with Bingo Stars for a few days, and from a technical standpoint, it's surprisingly polished. The UI is clean, no weird lag or crashes, and it loads up pretty quick – maybe 2-3 seconds on my iPhone. The API integration with the payment system seems solid too; withdrawals were surprisingly painless, which is always a plus. Under the hood, the game logic itself is pretty standard bingo, but the 'win real money' aspect definitely adds a layer of excitement. It's not gonna make you rich, obviously, but it's a fun way to potentially earn a few extra bucks while you're chilling. Plus, the dev team really thought about the UX; it's easy to pick up and play, even if you're not a hardcore bingo player. No spaghetti code situations here, thankfully! Barely uses 60MB of RAM, which is great because I hate when apps hog resources.
