Click on Bub to start a new game. There are 10 T-Rex hidden under the squares. Click on any square to start. If you see a 1, that means there is 1 T-Rex touching that square. If you see a 2, that means there are 2 T-Rex touching that square. If you think you know which square has a T-Rex, right-click on that square to flag it. If you click on a square with a T-Rex...he'll chomp his teeth at you and the other 9 T-Rex will appear.
