THE RULES OF THE GAME
The application shows you short sentences with or without mistakes. If you identify a mistake, you point it out by clicking on the word. A small robot pops up and comments on your correct and incorrect answers in an illustrated manner. If your answers are wrong a simple and an accurate explanation will be given to you. You can then listen to the sentence and read its translation.
Repetition is the key to learning. Therefore, 1 to 5 stars are associated with each level in order to encourage you to replay them and get 5 stars without making any mistakes.

A GAME WHICH ADAPTS TO YOUR KNOWLEDGE
Each level has 5 rules to remember. An algorithm automatically determines the rules which you may already know or not know, and chooses the type of mistake at each step to show it to you, giving priority to those that you have not yet acquired. When the algorithm determines that you have mastered a rule, you earn a star.

The total duration to complete all levels on average is 20 to 30 sessions of 5 to 10 minute games and it depends on your level.
