If you remember the old Space Invaders video game from 1978 then you have a pretty good idea of how the tutor works. Consonants and vowels drop from the top of the screen, and you have until the bottom of the screen to correctly type the answer. Your score is marked on the right, as well as some filters Glenn put in to help you concentrate on specific things. You can start, pause, and restart the game as you like.
You can play the game on thai-language.com, and sometime in 2010 I will be releasing another online Thai learning game (again on TLC or perhaps here on this blog).
