My Word Coach is a game that is designed to help you to improve your vocabulary.
Using several mini-games, you get to learn new words and their meanings. These mini-games include a Tetris-like block game in which you need to form words, or a section in which you have to match words to their meanings.
As you progress through the game, more mini-games are unlocked. Also, the game keeps track of your progress, giving you a score that improves as you play more and more.
