Publisher: Bit Corporation

Bit Corporation was a Taiwanese company that made Atari 2600 games and console clones in the 1980s. It sold cartridges under its own name and under the Puzzy brand, and its games appeared under many different titles around the world. In Germany, for example, the mail-order company Quelle sold them with German names, and in Brazil the company CCE released several. Most of the games date from 1982 and 1983.
