Cognido: A University Project Turned Thriving Brain-Training Game
Cognido, a fast-paced multiplayer brain-training game, is the brainchild of university student David Schreiber. This solo project boasts over 40,000 downloads, defying the typical fate of many university projects. It offers quick matches against friends and strangers, presenting challenges ranging from simple math to trivia and beyond.
The game's quick-fire format sets it apart. While not as cuddly as Dr. Kawashima's brain training games, Cognido's unique mascot, Nido, adds its own quirky charm. The game's success is a testament to its engaging gameplay and addictive nature.

Developed in Germany, Cognido offers both free and premium 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.
