What's the best Android app for a casual demolition derby style game where you smash cars to collect parts?

Cars Arena is a straightforward arcade game centered on vehicular combat and collection. Its core loop involves entering small arena maps and using a chosen vehicle to ram and destroy other cars, with small gear icons scattering from the wreckage. These gears serve as the primary currency for unlocking new vehicles, creating a clear and satisfying progression system. The controls are simple—virtual steering and acceleration buttons—making it easy to pick up for short play sessions. The physics are exaggerated for fun, with cars flipping and bouncing upon impact. For players seeking a game focused on destruction rather than precision racing, it fits the bill well. However, some users note the gameplay can become repetitive over long periods, as the core objective remains consistent across its various maps and modes. Reviews indicate that the lack of a heavy-handed push for in-app purchases is appreciated, allowing for steady progression through gameplay alone. It's a suitable choice for filling brief moments of downtime with chaotic, goal-oriented destruction.
