CryptoLogic was founded by brothers Andrew Rivkin and Mark Rivkin in 1995 from the basement of their parents' house. The brothers wanted to find a real life application for a secure online financial transaction system which they had developed.

Through a subsidiary company called WagerLogic, the company handles the licensing of its gaming software, support services and payment processing, ECash.

The company launched their first licensee, InterCasino, in 1996. Since that launch the company has made deals for several other online casino and online poker rooms, including one with William Hill plc, a leading bookmaker in the UK and the first land based operator to go online with a casino. A deal with Littlewoods Gaming led to the gaming software being certified in the Isle of Man in 2002 and Ritz Club certified by the Alderney Gambling Control Commission in 2004.

In addition to the casino and poker products, CryptoLogic also now offers online bingo software. Their casino games can be played in a downloadable and a Java based software version. CryptoLogic listed on the Toronto Stock Exchange (CRY) in 1998 and on the NASDAQ (CRYP) in 2000. In 2003 the company began trading on the London Stock Exchange (CRP) before achieving gaming software certification in Alderney.

Under Lewis Rose's leadership as President, Chief Executive Officer and Director from 2002 - 2007, CryptoLogic's market capitalization grew from $90 million to over $400 million, during which time the company became regulated, listed its shares on the London Stock Exchange, signed a number of leading global branded customers such as Betfair and the Ritz Club London, opened an office in Singapore to service South East Asia and won top industry awards for its innovative branded software and its 24x7 global customer support centre in Cyprus.

The Playboy brand launched casino and poker products on using CryptoLogic software in early 2007.

World Poker Tour Enterprises (WPTE) also joined the CryptoLogic network in 2007, offering both casino and poker products.
