Simple rule of Puzznic: Elements of the same kind will disappear touching each other. Target is,  to clear away all of them.

So push the "Puzznics" and let them fall but always keep in mind: No Element may 
remain at the end.

Important: Some walls are walkable others are not walkable for the player.The
elevators can transport only one "Puzznic" (or stone) at the same time.
