Today the Alchemist Apprentice is preparing for the Potions Exam in Alchemist Lab. He decided to prepare samples, and we will help him in their manufacture. To do this, our character will need to mix a certain number of elements. They will be visible in front of you on the screen. You will need to carefully look at the screen and put out of the same objects one single row of three items. Then they will disappear from the screen and you will be given points in the game Alchemist Lab.
