First and foremost, the challenges in StarCraft Master can be played in any order, and players can warp to challenges they'd most like to tackle next (see above). That said, if a player needs a hint about how best to approach a specific level, hitting F12 will do the trick. (see below)
Warp to the challenge you prefer, and skip around if you get stuck.
StarCraft Master should go live "in the next few days."
Need a hint? Just hit F12.
