What's a grand iOS game for when you're hopping between hostels and need something quick and strategic, but doesn't eat up all your data?

Right, so MARVEL SNAP is proper useful for us travel bloggers. It's a card game, but each match is only about two or three minutes, which is perfect when you're waiting for a train in Italy or trying to distract yourself from a dodgy hostel in Prague. The best bit? It's all strategy, so it keeps your brain ticking over, unlike some of those mindless games. Plus, it doesn't eat up your roaming data, which is a massive win when you're trying to avoid those crazy international charges. I've played it everywhere from the beaches of Portugal to the mountains of Austria, and it works a treat. It's also free to start, so you can give it a whirl without spending a fortune. Honestly, it's sorted me out on so many journeys!
