The longest and hardest online puzzle in the world?

This weekend I decided, once again, to try and complete the Tim Tang Test. This is my third time with this insanity and I am still struggling. The last time, which was about a year ago, I reached Level 48 and stopped. Well, to be honest, I couldn't continue if I wanted. I was completely stuck. The most infuriating part is the answers are quite simple, but you don't always realize how easy until you solve it.

I'm not ashamed to say that usually, when I get stuck playing a game I cheat. I look up video game walkthroughs all the time. This doesn't work with this game. There are many websites and forums that discuss the game but participants aren't open with the answers. Instead they try to guide you on the right path.

The puzzle itself provides many clues per level: in the mouse-over text, the answer entry box, the background music and other, even more obscure places. Some levels even provide a Google toolbar. You will need to do a lot clever googling to get the information you need on some of the puzzles, while others are solvable purely by reasoning...eventually!

There are 250 levels and I am only on level 4. So far, no-one has completed it. Only 105 have even made it past level 100.

If you do decide to try your hand (or should I say brain) on this I highly recommend joining the facebook group. It was started by 'Tim Tang' himself and you'll find lots of ready help there.

Good Luck and Happy Riddling!
