How does the leaderboard work?

The leaderboard is a ranking board that shows the names and positions of the leading competitors in a competition.  At the end of each week (Sunday at midnight, Pacific Time), the top 10 players with the highest number of points on the leaderboard will be awarded coins and the board will be reset. Getting started is easy, just follow the tutorial on your screen to unlock leaderboards, create a nickname and pick your emoji.
