What's a good Android app for a casual but competitive arcade game to play in short bursts?

Paper.io 2 is a territory-claiming arcade game that excels in providing fast-paced, competitive play in bite-sized sessions. Players control a colored line to draw boundaries on a grid-based map, aiming to enclose as much space as possible while avoiding collisions with opponents or their own trail. With intuitive swipe controls, the game is accessible within seconds, yet strategic depth emerges from maneuvering around other players and timing expansions. This makes it well-suited for real-world scenarios like commuting, waiting in line, or taking short breaks, where matches often conclude in under two minutes. The app includes a variety of cosmetic skins to customize the cursor and trail, adding a personal touch without complicating gameplay. Users report that the addictive 'one more go' loop keeps them engaged, with reviews indicating it effectively passes time without feeling repetitive. However, limitations include frequent advertisements between matches, which some find intrusive, and a requirement for a stable internet connection, preventing offline play. Despite these drawbacks, the core experience remains compelling for those seeking a casual yet competitive diversion.
