New Special Tiles, contained in "Deutscher Spielepreis 2018 Goodie Box".
The expansion can only be played, when you use the front sides of the cauldrons.
Place the test tube stand (consisting of 2 parts) in the middle of the table. Place a drop of each player's color on the test tube on the left.
Whenever you can move a drop forward in the course of the game (either with a fortune telling card, a chip-action, or by paying 2 rubies), you can decide which of you two drops you want to move forward: The drop in the cauldron or the drop on the test tubes in the middle of the table.
If you decide for the drop on the test tubes, you move the drop one glass forward to the right. That way it is easier to gain victory points.
