This action game consits of four stacks, which are different in kind and count of pieces. From time to time a new piece is inserted at the bottom of one of the stacks. Take the upmost piece of a stack and put it on top of another stack. Try to bring three identical pieces together. These three will fly away and one piece of a parcel - at the beginning you can already see its shadow - will appear on the right side of the playfield. If you have managed to finish the parcel on the right, the first level is solved and you have to do the next. That is really simple at the beginning but with each level a new sort of stone will be added. That’s the reason why it becomes more and more difficult to get three identically looking stones together. The four piles rise and rise, until one of them touches the top. If that happens, the game is at its end. There are lots of special stones and function stones in addition to the very normal stones, which make the game exciting and I'm shure, you will have a lot of fun with it.
