Mythlound : Maurlack Tower iOS game

After having cross the little road along the hill surrounding Maurlack Tower you finally reach your destination. But Maurlack was already aware that you will come and he won't let you stop his reasearch. As you enter Maurlack tower main chamber you're being warned that you will need to move the stone tile that he's sending your way before they collide in the magical archway. If you don't well, the only thing I can say is that terrible thing will happen to you...

But they are a way to survive this, by using your alchemy skill you can make those stone tile disappear by combining 2 of the same elements together that are hidden under each stone. Each pair of the stone tile that you transmute together will give you a certain amount of point, if you combine 2 that are side by side (left/right or up/down) you will get extra bonus point. Each time a pair of stone tile disappear from the room, stone tile above the one that just disappeared will slide down until they collide with another stone tile (don't worry you won't get any harm).

Also you have some special elements which you can use to help you in your quest, they are the "Crystal ball", "Jester", "Divine Intervention". But beware that Maurlack has also some other mean to make you fail in your quest... if you turn one stone tile that have the "Bomb" then all stone tile surrounding the point of impact will also explode (which mean you wont be able to turn them anymore or move them).
You will be game over once another stone tile collide with the one that is blocking the magical archway entrance of a new stone tile on the top. If not you have to get as much point as you can and get more elements which will eventually let you combine them together to form the philosopher stone...
