If you like traditional intelligence and skill games, you will enjoy the beauty with this complicated variant called Open Alchemist.
In Open Alchemist you get into the skin of a crazy alchemist who must try to properly place each of the objects related to alchemy that are falling. It is not enough to group them together to form a complete line (as in the Tetris), but you must do it by colors; Only when you get to have objects of the same color together will they disappear.
Of course, objects never stop falling in Open Alchemist, so you will have to be more skilled and faster to place them before they accumulate and, therefore, you lose everything.
You can free download Open Alchemist 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
