There is? :o
I have an idea too. So, there are games on websites, and maybe there can be a goal or something and you can earn points by playing those games.
Example:
2048 - 2000 points
T-rex runner - 1000 points
There can also be something like
2048 - 2000/5000/8000
So if you get 2000 points you’ll get 40 EXP, 5000 points = 100 EXP, 8000 points = 160 EXP…
