These achievements are gained via completing the T-Rex storyline. Your goal is to eat all the cars before they visit all the delivery locations.
- Keep bashing the button whenever you are heading towards a delivery truck. There is some sort of 'lock on' that will help you target the truck and it makes life easier.
- The first two levels are extremely easy because you do not have any competition.
- In the last four levels, you have one or two other T-Rex's competing with you for the trucks. When there are no trucks, run around while tapping and, with luck, the trucks will spawn next to you.
