Horrible. It's a obvious ripoff of Random Dice and Clash Royale. Has the same cost system, life number, merge mechanics, and card power ups in a round just like Random Dice. It also has arenas, pass, and upgrade system as Clash Royale. Random Dice has no ads for it, and is just better overall. Would recommend Random Dice over this stupid ripoff. Would rate Rush Royale a 0 star if I could. Apparently there was a update with limited coop plays, just like Random Dice always has.
