Cerebriti
Cerebriti is a Spanish app developer that has created apps such as Quizstory: Spanish Friendship, Esero SpaceTroopers, and Academons Elementary lessons. The platform gives access to a wide range of games that could be used in education, but most of the games are only in Spanish. In any case, this is a good resource to get instant access to ready-made games that can be used in the online learning environment.
