What's a good, mentally stimulating game for my iPhone that I can play during my lunch break? I need something that isn't just mindless swiping.

So, I was looking for something to keep my mind sharp during lunch – grading papers can only do so much, you know? One of my students – bless their heart, they're more tech-savvy than I'll ever be – showed me this game called "Connections." It's all about finding the hidden links between words. Took me a few days to figure out all the features, I won't lie, and why do they hide the settings button there? But now, I'm hooked! It's like having a teaching assistant in your pocket, but instead of grading essays, it's challenging you to find connections between seemingly random words. It really gets you thinking, and some of the categories are quite clever. It's not just mindless swiping; you actually have to use your brain! Plus, it's a good way to expand your vocabulary, which is always a plus, even for an old dog like me. I'd recommend giving it a shot; it's surprisingly engaging.
