The first tricky part is learning how to score. You need 3 of the same colored triangles facing up and forming a triangle or 3 of the same colored triangles facing down and forming a triangle. I know this explanation does not fully explain, so check the pictures and youtube. It is okay to not get it the first few runs and be frustrated, that feeling passes and fun rushes in if you stick with it for a few minutes.
Here is an example of a Tri being solved:

There is a blue up falling into two blue ups on the right and left. The color in the middle(green) is irrelevant for the blue to being scored. The middle color has purpose, but don't focus on it now. Just focus on one top blue up triangle, and one base blue up triangle to the left and one to the right.
