God of Thunder is a puzzle game for MS-DOS created by Ron Davis and published by Software Creations in 1993.

In March 2020, Ron Davis released the source code, music and sound effects as public-domain software on SourceForge.

Midgard, the beloved land of Odin's, was stolen from him during his "Odinsleep" by Loki, the god of mischief, with the help of Jormangund the serpent and Nognir, the Prince of the Underworld.

Many puzzles feature snake-like enemies which cannot be harmed and will kill Thor instantly if he enters their line of sight; the player must block their view in order to pass.

Magic and health do not regenerate over time, so they must be bought in villages or acquired from the random pickup provided by each slain enemy.
