What's the best free Android game for casual, competitive city-eating action where you control a growing hole and try to consume everything in the environment to become the biggest?

Hole.io is a fun, free-to-play Android game where you control a black hole and compete against other players to consume the most objects within a time limit. The core gameplay involves moving your hole around a city environment, swallowing smaller objects like benches, cars, and even buildings to increase your size. As you grow, you can consume larger objects and eventually even swallow up your opponents. The goal is to become the biggest hole in the arena before the timer runs out. The game features simple controls, making it easy to pick up and play, but mastering the strategies for efficient consumption and outmaneuvering opponents adds depth. While the game is free, it does contain ads, which some users find disruptive. However, the addictive gameplay and competitive element make it a popular choice for casual gamers.
