I downloaded and installed this game called Tiny Tower. You start with a lowly tower of 1 floor and aspire to build 100+ floors. Each floor can be designated as residential or commercial. People can move into your residential floors (up to 5 per floor) and can find jobs on the commercial floors (up to 3 employees per floor.) The commercial floors sell products and you collect the revenues. When you've made a decent amount of cash, you can build another floor, and each subsequent floor costs more money and takes more time to complete.
When I first started playing this game, I was quickly addicted but also found the pace a bit too slow. Floors can take days to complete and many commercial floors will require many hours before the products they're selling are fully stocked. It turns out, this pacing mechanism makes this game perfect for a 3-5 minute break from work. Sure, you may be hooked to this game but there's not that much to do each time you log in other than to reopen businesses, restock floors, check the status of your new floors and cash reserves, etc. A short play session can easily be squeezed into your breaks if using the Pomodoro Technique.
Try it out and you'll know what I mean. If you love business simulation games like Farmville or the classic, Sim City, then you'll definitely love Tiny Tower.
