Arenas

Arenas in ScrapTD are a good way to show the skill of a player. Depending in the Trophies a player has, he will be in an arena or in another one. If you get an arena higher, you will have x1.1 as much Bricks and more Magnets every time you win.

You can get matched with people who have less than 1600 trophies of difference between you and them (it is higher in high trophy zones).
