WaniDoku is a vocabulary game that can help you to improve your reading and writing skills.

It is based on a simple principle: if you are reading a sentence and you don’t know a word, you will not know what the sentence means, and you will not be able to understand the sentence.

In order to make sure that this does not happen, the game uses a technique that is very easy to learn and use: the app will display a notification with a word that you do not know, and you will be able to translate the word into your language.
