ディグダグ
"Dig Dug" popularized a short-lived trend of "digging games" following its release. There were a number of "Dig Dug" clones at the time, such as the arcade game "Zig Zag" (1982), the Atari 800 game "Anteater" (1982) by Romox, Merlin's "Pixie Pete" and Victory's "Cave Kooks" for the Commodore 64 in 1983, and Saguaro's "Pumpman" (1984) for the TRS-80 Color Computer. The most successful digging game that followed it was Universal Entertainment's arcade game "Mr. Do!" (1982), released about six months later, which made changes to the formula that went beyond a clone. Sega's "Borderline" (1981), when it was ported to the Atari 2600 as "Thunderground" in 1983, was mistaken for being a "semi-clone" of "Dig Dug" and "Mr. Do!" "Boulder Dash" (1984) also drew comparisons to "Dig Dug". In more recent years, there have been numerous digging mobile games based on "Dig Dug", either as clones or variations on its formula, such as "Diggerman", "Dig Deep", "Digby Forever", "Dig Out", "Puzzle to the Center of Earth", "Mine Blitz", "I Dig It", "Doug Dug", "Minesweeper", "Minecraft", "Dig a Way", and "Dig Dog".
