O'Riley's Mine is an action game designed by Mark Riley and published in 1983 by Datasoft for Atari 8-bit computers.

"[4] The Addison-Wesley Book of Atari Software 1984 gave the game an overall weak rating (D+) and didn't like the price: "Despite its simplicity, it might be worth looking at, but not at $29.95.

"[5] Computer and Video Games, reviewing the Commodore 64 version, praised the graphics and called the water sounds "quite realistic".

[6] Joaquin Boaz, writing for InfoWorld, drew comparisons between the Atari arcade game Dig Dug and stated O'Riley's Mine, "makes excellent use of both water and the fear of it."

Boaz also noted the package's inclusion of both a floppy disk and a cassette tape as "a nice touch".
