SLACKERJACK – 10 Gnomes
10 Gnomes couldn't be easier if it was made of Duplo. In theory. There are 10 gnomes and you've got to find them.
Of course, what you're not told is that the 10 gnomes are about a millionth of a pixel tall and the bastard thing's almost completely impossible, but you'll figure that out for yourself after you've played 10 Gnomes for 15 minutes and your eyes are sore.
Annoying.
