A free app for Android, by Philip Nguyen.
The app has four different versions. In the first version, you can choose the language of the game: English, French, or Russian. The app has a dictionary with over 300 words. If you can't figure out a word, then you can use the built-in search function. You can also set the level. Each time you go to a higher level, you have more difficultly to play. Each level has a practice function. You can use it when you need to practice. You can also go back to the previous level, if you feel like it. In the fourth version of the app, you can disable "Auto Advance".
