Simple Pair is a 1995 memory card game: turn cards face up, find matching pairs, clear the board. The rules take seconds to explain and a game lasts a couple of minutes, which is exactly the format that filled Windows 3.1 shareware collections.

It was released by Jörundur Sveinn Matthíasson, by available accounts an author from Reykjavík, as part of his set of five games from 1995. Icelandic hobby games from the 1990s are thin on the ground and this series is one of the few surviving traces, though the Icelandic origin follows mainly from the author's name. We file it under DOS, but the executable itself targets Windows 3.1.
