What's a good iOS game that's not just mindless tapping, but actually helps me think strategically and plan ahead?

Look, I don't have a ton of time to waste on games that don't offer some kind of mental workout. Grand Hotel Mania is actually pretty good at this. You're running a hotel, managing resources, and trying to keep customers happy. It's more involved than you'd think, and it forces you to prioritize and think a few steps ahead. It’s like running a real small business, but without the late-night calls from the plumber. Plus, it’s a nice distraction when I need to clear my head between deals. The graphics are decent, and the gameplay loop is addictive enough to keep me coming back. Bottom line: it's a solid way to kill some time while still feeling like you're accomplishing something, even if it's just virtual.
