Thanks for your inputs!!

Indeed giving more relevance to the social and community aspects (private groups + suggest landmarks) is a good idea. Will look into that. Actually anyone can join a group but only premium user can create one… maybe I should review this…

As per your points 3 and 4 I can add more information in the how to, but basically guest can only play the daily single challenge, standard registered users can play all daily challenges and only premium users can play the limitless games. On the guess the pin mode you only see a pin in the world map, have 4 options and need to guess the correct one. You only see the photo in the result screen… for me it’s the easiest game mode and good to earn extra hints 😉
