Tim tang test is another online riddle game, which says it is the longest and hardest online puzzle in the world with 200 levels and more coming levels. "remember, the answer to each level gives the url for the next level. it is placed right after the last slash in the url. for example, the answer for the next level is level1.html, so what you would do is replace the level0.html in the url with level1.html, so the next level's url becomes ttt/level1.html. once you find the answer to that level, you replace the level1.html with answer.html, whatever the answer is. it's not case sensitive so don't worry about capital letters, level1 or level1 both will work." good luck!
