Get ready to defend yourself, because a lot of dinosaurs are coming for you!
A caveman was in the middle of an attack of dinosaurs, it is your duty to help him survive. Now you are in charge of resisting all the dinosaurs that you can. Click on the dinosaurs with your finger to crush and eliminate them before they eat the caveman.

There are many dinosaurs that you should take care of.
Tyrannosaurus rex is very aggressive and resistant but it is not as fast as a carnotaurus, the brontosaurus is the most resistant in the game and although it is not aggressive it can cause you many problems, hit it as soon as possible.
The triceratops although they look very cute can reach you with their great resistance and cover the velociraptors behind them.
