Mybrute is a very cute, 5 minute, online game. You create an account, generate a character and then you are set to battle in the arena. You get 3 turns a day, which is actually perfect if you have a busy schedule and you want to be able to match you addict friends. Every time you level up you get either an ability, weapon or pet to help you in combat.
When selecting an opponent in the arena, you only see the person's stats ( strength, agility and speed) and not their weapons, abilities or pets. This makes it more of a gamble, because the opponent might appear weak and then all of a sudden the guy rips out a huge bear, bombs, ninja stars or an axe, with the additional extra thick skin ability.
