This Keeper card works in any Fluxx deck. It is functionally exactly the same as The Computer in Star Fluxx, and the Batcomputer in Batman Fluxx, though, because this card was produced much earlier than either of those versions, the art is not as fancy. (BMO, in Adventure Time Fluxx, is similar, since it's a computer... but I guess it's not as powerful as the others, since it only gives you the increased Limits, but not the additional Draw and Play)
For the player who has this card on the table, the numbers for the Draw, Play, Hand Limit and Keeper Limit rules all increase by 1. (The Computer also counts as either the Toaster or the Television (but not both simultaneously) for the Goal in original Fluxx called The Appliances.)
This card was released in early 2007, as an online exclusive -- you had to use a computer to get The Computer -- celebrating what we call the Ultimate Symbol of geekiness.
It used to be free with any order over $25 (and we gave away 2366 that way) but after we upgraded our shopping cart to a different system, we made these available for direct purchase.
