The situation is that I spend 8 hours a day on a PC that I do not have admin rights to, so I cannot install anything on it. I have a couple of games that boot directly from my USB drive but I can't just play the same hand-full of games forever. I have been trying to find a source that sells games that are tailored to boot via a USB drive and without administrative rights, something legit. I don't have much down-time but I beat Plants vs. Zombies, Solitaire makes me sick, and Minecraft gets old fast. I mostly want puzzle games that have no plot and so on. Something I can just stop and start whenever or play for a minute while waiting on customers. Anyone know any good sites or anything?
Also, I'm not interested in games that launch via the browser. There are tons of low-quality flash and java games out there and they are all pretty much the same.
