In their adventures across the planet of Kreludor, Gorix and Cylara uncover a mysterious door covered with symbols. They don't know what is inside, it could be treasure, or more importantly - clues that will help them find the secret of Kreludor and defeat the evil Dr. Sloth.
To play Time Tunnel you have to work out what secret code of four coloured stones opens the door. You have twelve tries in total. Click on each stone to change its colour, and then press UNLOCK to submit your guess.
Once you have guessed the door will tell you how close your guess was to the correct answer. A Yellow mark means that the stone is the correct colour, but in the wrong position. Each Green mark means that it's the correct colour in the correct position, and a white coloured mark simply means an incorrect stone.
