Dropbox's challenging multi-step internet scavenger hunt is back in 2012, and the company has upped the grand prize to a hefty 100GB of cloud storage for life, along with some tangible goodies. Dropquest II involves a series of puzzles that Dropbox says were inspired by MIT's mystery hunt and notpron — which bills itself as "the hardest riddle available on the internet." Dropquest isn't nearly as time consuming, and Dropbox says that everyone who completes the challenge will win at least 1GB of space. Just be warned: asking for help on the company's support forum will earn a disqualification. If you're ready to stretch your brain for storage space, head on over to Dropquest II's site and get to work.
