Mr. Do!

Mr. Do! is a 1982 maze video game developed and published by Universal Entertainment for arcades. It is the first arcade video game to be released as a conversion kit for other cabinets; Taito published the conversion kit in Japan. The game was inspired by Namco's Dig Dug, released earlier in 1982. Mr. Do! was a commercial success in Japan and North America, selling 30,000 arcade units in the US, and it was followed by several arcade sequels.
