IGT, on the other hand, is more well known for its physical slot machines for land-based casino gaming than virtual slots. together with Bally, IGT has been the behemoth of land-based casino slots for decades. However, the rise of virtual slot games and the versatility of multi-game machines in brick ‘n’ mortar casinos have had an effect. Not so much that they are in danger of going out of business or anything though. IGT still turns out top titles like Hexbreaker, Charlie’s Angels and Cleopatra.
