Cognido: A University Project Turned Brain-Training Hit
Developed by university student David Schreiber, Cognido is a solo-developed, multiplayer brain-training game that's already amassed 40,000 downloads. Offering fast-paced matches against friends and strangers, it challenges players with progressively difficult problems ranging from simple math to trivia and beyond.
This solo project, reminiscent of those often-forgotten university assignments, has defied the odds and achieved considerable success. While not quite as heartwarming as the Doctor Kawashima brain training games, Cognido, with its unique squid-like mascot Nido, provides a stimulating and competitive experience.

Made in Germany and Available Globally
Unlike many university projects, Cognido offers both free and premium gameplay options. A subscription unlocks the full potential of the game, but a free trial allows players to test the waters before committing. A significant update is on the horizon, introducing a new "Clash" mode for four to six players.
