Dragon Island Blue Hints for iPhone/iPad
It is only possible to have three monsters in action at any one time but if you use ALL of the beasts in your collection at some point it ensures that they ALL gain Experience.
Always keep an eye on your monsters stamina so you can visit the nearest town whenever they are running low.
Put a weak monster in the first tree then put the two strongest to guard weaking until it evolves or get in higher lvl
If you lose a level in the tournament (other then the first level in a set) then you can set the day forward by one, and the previous levels will be open again, and you can get more eggs this way.
