Every week, a new challenge is issued by taking a specific wave that a high rated player leaked on. The goal of the puzzle is to reposition the given fighters to beat the original score of the player.
Clearing the wave will grant 100 points. Every gold that is not spent will give an additional point.
If you manage to beat the score of the original player, then their name and build will be revealed to you. You will receive a Challenger trophy and 1000 . The top 100 scores receive an additional 2000 for their efforts. The top score each week also earns a Challenger Elite trophy and an additional 5000 .
