Gambling Federation is a casino software provider that has achieved rogue status over the years for not paying players. Their history of rogue behaviour is well documented and players should avoid these casinos at all costs. The software is now called CGTV Games which is essentially the same company, or rather according to BeatingBonuses.com they acquired Gambling Federation. The domain is currently offline but listed as owned by Ever88 Entertainment N.V. or ever88e.com. There are not many casinos running the software and any casino with it should avoid at all costs.
The history of Gambling Federation (also known as GFed) is a very long one as the site was first online in 2001 and was setup as an online casino software company offering casino games in Costa Rica.
