Money cheats

Money cheats are available in all The Sims games.

klapaucius & rosebud
The Sims has the cheats klapaucius and rosebud. klapaucius only works with the unpatched version. They both give the current household an additional 1,000 Simoleons.

Also, with this cheat, it's possible to type in klapaucius or rosebud, then a number of ";!"s next to it. Each of these gives an additional §1,000, so the more you put in, the more money the family will get.

Trivia
Klapaucius was one of the "constructors" in Stanislaw Lem's The Cyberiad.

Klapaucius was probably changed since it was too hard for players to remember.
