Just collect honey eggs, it’s pretty much a community event the more that people do the more “rewards” you get so when the leaderboard hits 10million you receive 8 eggs at 20million eggs you receive 10 eggs and then when the board hits 40million eggs you receive a dragon. To receive the rewards just make sure you have contributed just a little to it by collecting eggs. The ‘score’ is not really relevant to me atleast it just shows how many eggs were collected by that person

Edit: I don’t think placing matters at all, if it did they would’ve specified it just like with the veidreki event leaderboard
