Merlin's Lab

Merlin's Lab is a puzzle game in which you try to find the philosopher's stone

The closer you to the final aim, the more points you score. You create new items by matching three or more game pieces: combine Ginseng turns into Potions, Potions into Infusions, Infusions into Puner, and so on... until you've filled the board with crystals, pure elements, and maybe even Philosophers Stone itself. Along the way, you'll have to outwit Homunculus who will try to block your progress. How far can you go to find it? How many Homunculus had to be born before you were able to solve the greatest Alchemy quest?
