I have a bunch of coins that we earn for every game what are they for?
I was wondering the same thing. Lol
Coins are used for upgrading your units to a higher level for more health and damage. Higher levels will require more coins. Tap on “Upgrades” on the left-hand side of the screen.
The green bars represent how far you are into being ready to upgrade your units or commanders.
The bar represents how many unit cards you own for that particular unit or ability. As you level up those units, the number of cards you need to upgrade additional levels will gradually increase.
The bar represents how many of the pre-requisites for upgrading the commander to the next level that you’ve met . These pre-requisites usually involve acquiring a unit or ability card and leveling it up to a certain level. Tap on the commander to see what the requirements are.
