This HoH competition is called "Color switch"
For this challenge, you must play this game and screenshot your highest score:

You can only send your screenshot once, so choose carefully.
The two scores you and your partner send will be combined and the pair with the highest combined score wins the competition. The indidvudual with the highest score overall wins the HoH. If there are ties random.org will decide the winner (and I'll learn how to use it by then xD)
ALSO: The score you're submitting must be under the "Score" bar, not just the "Best score" bar. This prevents people from using previous scores if they already have the app. So if you think you got a good score, screenshot it right away. In the screenshot, I would also like to see another tab with tengaged.com.
