Ball Eating Simulator is a three-dimensional IO-style battle arena game that features anthropomorphic balls similar to the Pac-Man game character. The rules are similar to snake and worm games. The player must direct their avatar to eat pellets and smaller balls to grow to the largest, most deadly size in the arena.
If the player views an advertisement, they automatically grow their ball to more than 10,000 points in size at the start of the game. From there, they use the controls to direct it to eat colorful pellets and other balls as it moves across a two-tone green checkerboard field nestled between gray rocky hills covered in moss and fir trees. They also direct it to pick up temporary shields and speed boosters.�
Ball Eating Simulator offers a lot of fun extras. The player can claim gifts and special spin wheel prizes, including coins, extra points and additional spins. If their ball becomes the largest one in the arena, it receives a floating crown that shows off their achievement and warns away other balls. If it dies, they can view an ad to revive it or even seek revenge. Over time, if they earn enough money, they can upgrade their ball's color and gender and outfit it with special items (i.e., hats, toy weapons and facial accessories like sunglasses or a mustache).
