JUST DANCE 2015

When you're at the dancer selection screen of a song, hit the top right button that says "Add Challengers." The game will then add players that submitted scores online. Generally they will fill up the empty spots so you'll have up to 5 other scores to beat (3 others on routines with 4 coaches). When you finish the song, hit the top right button that says "Send Challenge," and it will send challenges to all the players whose scores you beat. Obviously, this means you gotta dance well enough to be able to send score challenges. Beat 100 other people's scores and send challenges to unlock this achievement.

I recommend you toggle Challengers on and off to cycle through challengers. You want to avoid players that begin with "JD" and your own High Scores since they cannot be challenged. I also recommend you just make sure Challengers are on whenever you play a song so you don't have to grind as much later.

Warning: I have noticed that the game scales the challenger difficulty based on your high score on the song. For example, if you 5 star "Problem," it'll give you challengers who have also 5-starred "Problem," most likely with an even higher score than yours. So if you've 5-starred every song on the game, I've found a solution to grind out easier challengers.

Play any of the Community Remix routines. Since the game doesn't seem to track high scores of the Community Remixes, it's less likely to give you higher scores to beat. At least, that's what I've found in my experience. As long as you know the general routine of the song, you'll be able to 5 star it easily. I recommend the song "Happy" because the routine is pretty simple, but there's a new Community Remix every few weeks so always check the JD Wall for any updates.
