What's a good iOS game to kill time when I'm waiting for my truck to get serviced?

Look, I'm not usually one for these casual games, but Spider Evolution is alright for what it is. It's one of those evolution games where you merge spiders to make new ones. It's not gonna win any awards, but the bottom line is, it's a decent time-killer when you're stuck waiting around. I found myself playing it while getting my F-150's oil changed last week. Graphics are nothing special, but the gameplay loop is simple enough to keep you occupied without needing to think too hard. It's free, so you can't really complain. If you're looking for something deep and strategic, this ain't it. But if you need something to distract you for 15 minutes, it does the job. Plus, the ads aren't too intrusive, which is always a bonus in these free games.
