Some facts about this game

Could be because you are living in the dinosaur age with no internet at all!

You can reduce your frustration by playing this game if there is an internet outage instead of staring at the offline page as in Internet Explorer.

The T-Rex image and sound designs were done by Google Chrome designers Mr.Sebastien Gabriel, Alan Bettes and Manuel Clement where the game was entirely coded by Mr. Edward Jung.
