This is memory tool to help people who are already familiar with the Thai alphabet memorize consonant classes, live and dead syllables, and the never-in-final position consonants. There is no other memory aid like it, and it will greatly improve your knowledge of the Thai language.
Select letters by stepping on the Trigger Devices. The letters you choose will display on the main skyboard.
Go to the Blackboard Device area and select the category you wish to study. It will reveal if your choices were correct.
When done, reset the system and keep doing it until you memorize the category. Enjoy!
