Heureka-Klett

Heureka was a German software engineering company which has made several personal computer games of the sort called "edutainment". They are point-and-click puzzle-adventure games, heavily inspired by "Myst" for Windows and Mac. These were distributed by Tivola International to be localized for many markets.
On June 1, 2005, Heureka-Klett sold its edutainment software to BrainGame Publishing. The holdings and marketing rights of the 22 games in their back catalogue were transferred.
Seven games in the educational series collectively sold over 500,000 units and won numerous awards.
Titles published.
Before turning to edutainment only, Heureka-Klett published also a school version of The Interactive Geometry Software Cinderella.
