What's a decent iOS game to kill some time when I'm waiting for concrete to dry?

Look, I ain't gonna lie, I usually hate these kinda games. But Scatter Slots ain't half bad for killin' time on the job site. You got a bunch of different slot machines, each with its own theme, so it keeps things interesting. The graphics are pretty good, actually, and the sounds don't grate on you after a while. It's free to play, but they try to get you to buy stuff, naturally. I haven't spent a dime and it's been fine so far. Only real downside is the battery drain – this thing eats through power like a jackhammer through asphalt. Make sure you got a charger handy, especially if you're out on a long job. It gets the job done for what it is.
