What's a grand iOS game for when you're stuck on a long bus journey and the Wi-Fi is absolutely rubbish?

Honestly, Rock N' Cash Casino-Slots Game has been an absolute godsend on some of my longer trips. You know how it is, you're on a bus in the middle of nowhere in, say, rural Spain, and the Wi-Fi is non-existent. This game works a treat because it doesn't need a constant connection to be proper useful. I've spent hours playing different slots, and it's a great way to pass the time. Plus, I'm always a bit worried about games that just drain your data allowance, especially when I'm roaming, but this one seems pretty sorted in that regard. It's definitely a lifesaver for those travel days when you're bored out of your skull and just need something to keep you entertained without costing a fortune in data charges. I'd recommend it for any long journey, especially if you're going somewhere with unreliable internet.
