This is Clozemaster in a nutshell. It teaches languages through games, in particular a “cloze test” which consists of a sentence with a missing word. Your task is to fill the blank with the right word based on context.
Clozemaster used to be a free language resource, but they recently switched to a paid model. Although you can still complete a few sentences per day, in order to really use this resource effectively you’d have to pay.
