A Club Penguin Private Server (more commonly abbreviated as a CPPS), is an online multiplayer game which is not part of Club Penguin, but uses Club Penguin .swf files, a database, and programming code in order to create an environment similar to Club Penguin. It is legal to play them, but it is illegal to host one if you make profit out of it. Previous popular CPPSes were shut down due to Disney approaching them and demanding that they either shut their CPPS down or they would be sued.
- CPPS' were originally invented by Alex Rath (iRath) which was the creation of iCPv1, the first ever CPPS. The main members of it were iRath, Lofhy (Co Co), Andy, Pengocent, Stanley, Myles and Patrick (now known as Bane).
- This CPPS became iCPv2 which closed down due to high traffic.
- From this Charles and others from PCL developed iCPv3 meanwhile Flappi282 (now known as Jamie) and friends started working on the OpenCP source.
- iCPv3 got over 300,000 users then was attacked by legal issues off Club Penguin causing them to shutdown.
- After this the OpenCP source became public as well as other minor ones which caused others to make their own CPPSes.
- Atlantic Penguin was the biggest and most popular CPPS, until it got closed on October 27th of 2013, putting CPPS.me in the first place.
