Cognido: A University Project Turned Thriving Brain-Training Game
Developed by university student David Schreiber, Cognido is a solo-developed multiplayer brain-training game that's already amassed 40,000 downloads. This fast-paced game pits players against friends or strangers in quick matches, offering a range of challenges from simple math equations to trivia and beyond.
The game's success is hardly surprising; brain-training games have a proven track record. While Cognido's mascot, Nido, might not possess the same comforting charm as Dr. Kawashima, the game's engaging gameplay and quick matches offer a compelling alternative.

Made in Germany and Available Globally
Unlike many university projects, Cognido offers both free and premium gameplay options. A subscription unlocks the full Cognido experience, but a free trial allows potential players to test the waters before committing.
A significant update is on the horizon, introducing a new "Clash" mode. This mode allows for larger-scale competitions with four to six players battling it out to be the ultimate brain champion.
