start with the top one
to win the game you must have all the heart stones (once you have them all and complete the quest by talking to the guy you can where the heart stones as a jewelery thing) and then go to the bottom right part of the area that is part of the red castle island thing and there will be to spell casters and 1 swordsman (you don't have to kill them)and behind them there will be a big swordsman and you have to kill him then return to the guy/gal who gave you the quest an you win!
(WARNING: you should save right be fore you finish that quest if you ever want to return to that point or play again with the hearthstone ever again this info waz from personal experience! )
