Single player

How do you unlock more single player wars

More than what? Sherbert Towers is the last one.

there are 50 single player missions. after you complete them all there is no new onces..

to unlock a mission you must get atleast 1 star in the previus mission.

I guess you mean how you can unlock the rest of the missions after completing the first two missions in the tutorial... not sure though.

You always have to gain at least one star or more in a single player level to unlock the one that comes after it :)

So if you're stuck in a certain level, you need to try it as long as you need until you managed to get one star or more in it, so that you're able to get to the next level.

You can play any level as often as you want though, just there won't be any loot again after you got all of it already. :)

Have fun managing all of those 50 levels ;)

If you have completed all the single player maps, then there are no more. You cant unlock any.

If you have not completed all the maps, to get to the next level, you need to beat the level you are currently on.
