Today there are more than a dozen companies competing for floor space in casinos around the world. In 2019, however the competition weeded out two companies that had been the technical innovators. Following is a list of the mode important slot machine manufacturers, including the two that were gobbled up by the bib boys.

Bally Gaming Systems

Bally is the oldest of the current crop of slot machine manufacturers, and can be credited with a number of firsts. In the early 1960s, they successfully marketed an electromechanical machine. followed by the first multi-coin slot, the Game Maker.

The multi-game Odyssey series were advances technology machines with superb graphics and excellent sound. To accomplish this they utilised a fast hard-drive, a CD-ROM drive, and a Pentium processor, which made the machines expensive to produce. Consequently Silicon had trouble staying in the black and was ultimately bought out by IGT in 2001.
