What are timed boosters and how to use them?

I am on level 1318 stuck in this game last week unlimited life was given but I didn't get enough of it. It was so boring that I am thinking of abandoning this game. I came a long way in this game only to find myself getting it difficult to pass simple level. I got no blast and even my bot once I but when I lost it all gone I have to start all over.infact I don't understand this crushing game any more. Pls can anyone help me out before I abandon the game for life .

Timed booster is really useful & helpful.

Mm

Hey crady

That's what gold bars are for, is ti buy things, the higher your score the high you go on the leader board, and you win boosters at the end of the week, or the end of the contest..
