It's a one round, but long (like 25-60 minutes, mostly around 45), loads like Rumble fighter in the beginning and can be single, 3vs3, or 5vs5. If your ping is high, it may get laggy. You can easily leave and return if you dc but cannot go onto a different game until that game ends. When you die, you will be revived depending on the current time of the game. Real money is not needed at all!!! All Champions/Characters + Runes (A somewhat build/buff) are free. Real money is used to buy Champions (so you don't need to save money for it) and Skins. You can play any champion, but some are overpowered and some are underpowered. (Sona is called an overpowered character, but i don't believe it since she's a pure support.
