We can collect 600 coins in each timewindow. We start with 600. That will be in total 6000.

Dragons:

Never Grow #462

Berserk #680

Seducing #643

Cursedglow #1038

We made 2 maps. (Mobile and PC are different, so we have 4 maps in total)

The first one is for Cursedglow only . It will cost 6530 coins skipping tutorial, with tutorial 6735.

The second map is for Never Grow, Berserk and Seducing. It will cost 6365 coins. If we skip Never Grow we save 410 coins, so we can get Berserk and Seducing for free.

My tip is to wait with walking to see if we perhaps get a quests or videos to get more coins.

Edit: We found cheaper path for Cursedglow. Check the new maps.
