"The Contestants has escaped the crayon box af they where eliminated but they ar armed aswell so now you have to fight back in this old like game"
That's basically unreadable, but I'll try to help you out with what's wrong:
Contestants isn't a proper name, and shouldn't be capitalized.
It is also plural, so should be followed by a plural, not a singular.
1) have instead of has
4) comma after eliminated, and before but.
4b) You could also do a period, and eliminate the but, and capitalize They.
This would break up your run on sentence.
aswell isn't a word
6) as well instead of aswell
7) Period after well.
8) Eliminate the word so, capitalize Now.
9)Sort of fixed
The contestants have escaped the Crayon box after they were eliminated.
They are armed as well.
Now you have to fight back in this old style game.
I think that is what you meant?
You could change the middle sentence to read:
They are also armed.
This should be easy to edit, and I can remove this text once you have fixed it.
