Shiritori (しりとり) is a Japanese word game in which the players must say a word that begins with the final kana of the previous word (see description on Wikipedia).

This proposed implementation of this educative game, which requires some minimum knowledge of the Japanese language, provides a fun way to enhance your Japanese level and produces some personalized data that allow you to follow your progresses.

It should foster the learning of new words. Furthermore, when you lose, the system checks whether or not you knew some suitable words, and show you the list if any (to achieve this, the system remembers all the words you have used so far).
