Behind the scenes of the major poker rooms sits a range of poker software suites that are downloaded to your computer and used to monitor every hand and bet played. Not only are they highly advanced in terms of customer features but they are full of sophisticated anti-fraud routines and regularly audited by top consultancies.

Here are the main developers who create the poker software experience:

Microgaming
The first company to develop a fully operational online casino system in 1994 and is seen as one of the leaders of this type of poker software. The software has a vast range of features and credible performance.
As a company they operate on the board of many of the regulation authorities and run a vast array of marketing and networking events in the industry.

CryptoLogic
These guys have created similar poker software to Microgaming and operate poker games through their subsidary Wagerlogic.

Tribeca Tables
