So if you are interested in knowing how you earn points and haven't figured it out then here you go!:
Step one- Click on your name in the upper left hand corner and then click on your name again (circled in red)
Step 2-Click on the points link under your name (again circled in red)
After that you should get a screen like the one below showing your current points and how they are accumulated and multiplied!
Now just need to find the different tier amounts!
