(Extracted from the game)
XBill-NG has been painstakingly designed and researched in order to make it a hard to use for the whole family as it is for geek Linus. Years - nay - days of beta testing and consulting with the most hardest of human interface designers have resulted in a game that is somehow hard to use, yet nothing at all like *NIX.
I. Whack the Bills (click)
II. Restart the computer (click)
III. Pick up stolen OSes & return (drag) them to their respective computers
IV. Drag the bucket to extinguish sparks
V. Scoring is based on total uptime, with bonuses for killing Bills, and random numbers so you can score more.
As for the rest, you can probably figure it out. We did, so it can't be too hard.
