Am I fighting bots?
You will only fight against a bot if your internet connection is not good enough to sustain the stable connection with another player. If you want to check whether you fight a bot or a real person, you may try to pause the game in the middle of the fight. If the game stops, then you are fighting a bot. If it doesn’t … well you’d better get back to punching or your real opponent might use that moment to knock you down.
Another tip: when you take a look at the friends section, the ones that are online at the very moment have a green border around their profile photo. This means they are ready to be crashed. Or crash you.
