Essentially, the game allows you to costume your warriors and play a really fun dice based genre. The game costs a little bit of money but is well worth it for something so quick and easy that takes no time at all. These warriors, when merged together become randomized. When merging two of the same warriors you get a new random color warrior with a boosted strength. This is a feature that's built into the game. Players can upgrade different units on their team, though units won't be affected after being merged. #rushroyale
