What's a good iOS game to play when I need to unwind but also keep my mind sharp between showings?

As a real estate agent, I'm always looking for ways to de-stress and recharge between appointments. I need something that's not too demanding but still keeps my mind active. Otium Word Search is perfect for that! It's like a mini-vacation for my brain. The puzzles are challenging enough to be engaging, but not so difficult that they cause more stress. I can easily play a few rounds while waiting for a client to arrive or during a quick break at the office. It's also a great way to improve my vocabulary and spelling, which can come in handy when writing property descriptions or communicating with clients. Plus, it looks professional enough if a client happens to glance at my iPad Pro while I'm playing. It's a win-win!
