Hey there. I'm running a contest to drive users to my game and am offering free concert tickets to the top 5 high scores in the game (given a specific time and date for high score completion). What is the easiest way to identify which game players are new vs. which have been playing for a while?
Also, I currently have 30 levels within the game, and I see 30 individual leaderboards. Is there a way to identify the highest scoring players overall? or am I restricted to level by level?
