Merge Legend

See all those precious stones? 

Find the intersection points of two gems of the same color, merge them, and, voilà! Now you have a gemstone that is even more precious! 

But, wait! Where does that path lead to with all those precious stones?

Keep finding the intersection points, merge gemstones, and clear the path before they reach the grinder. 

Can you manage to match all the gemstones on the path before destruction ensues?
