Chemicus: Journey to the Other Side is a 2001 educational adventure video game by Heureka-Klett as part of Tivola's "Quest for Knowledge" series.

The player is a friend of Richard, a chemistry lover who is falsely accused of stealing a treasured item from the land of Chemicus after he arrives there in a portal.

[4] Adventure Archiv thought the puzzles were fastidiously designed and that chemistry concepts were seamlessly integrated into the gameplay.

[9][10][11] Just Adventure noted that while there was an overarching goal, there was no plot-related logical reasoning given for the player to complete each individual puzzle, besides the fact that they can't progress to different areas until they do.
