So here we are being logical

I love these, especially when they're in text form without the handy little pre-prepared tables!  Thanks Fergus.

There are 5 adjacent houses. Each house has a unique color, and each owner has a different nationality. Each owner keeps a different pet, drinks a different type of beverage, and has a different occupation. The Brit lives in the red house, the Swede keeps a dog, and the Dane drinks tea. The green house is on the immediate left of the white house. In the green house they drink coffee. The postman has birds. The fireman lives in the yellow house. In the middle house they drink milk. The Norwegian lives in the leftmost house. The baker lives in the house next to the house with the cats. The fireman lives in the house next to the house with the horse. The bus driver drinks beer. The German is plumber. The Norwegian lives next to the blue house. They drink water in the house that lies next to the house where the baker lives. One of the owners keeps a zebra.

Who owns the zebra?

So here we are playing SNAFU tower defense

Warning : SNAFU TD is the reason that you will get nothing done today!

SNAFU TD is like other TD games : You are in control of a map, across which enemies (usually in increasing levels of toughness) will march. Your job is to strategically place towers (ie weapons) that will then automatically shoot down your enemies. The difficulty resides in placing the towers in a such a way that you maximize the full effect of each weapon and, cucially, do not run out of space as the map is finite.
