Pie.ai is a multiplayer endurance game where you have to stay away from the red zone that eats different players. Flying machines display random red zones to the driver; stay away from them no matter what or it's game over. You can eat different players to get 200 calories, but be careful: they can try to eat you too! Eat different items to get extra calories. In case you are low on energy, eat an energy item and bounce into it to restore your energy. Best of luck!
