What mobile games offer substantial content, fair monetization, and offline play?

[BrianJ]

I'm looking for new mobile games that are genuinely engaging and not just filled with aggressive microtransactions or ads. I enjoy strategy games, RPGs, and well-crafted puzzles, but I'm tired of downloading something only to hit a paywall after an hour. For other gamers who primarily play on their phones, what are the best mobile games you've discovered recently that offer substantial gameplay, a fair monetization model, and don't require an internet connection to enjoy during a commute?
