Coreball is an online arcade game published by Arealme.com, where players test their timing and precision by launching balls at a rotating central core. The objective is to attach every ball without hitting those already orbiting the core, then progress through increasingly challenging levels. The original game has been available on Arealme.com since 2015 and now offers 500 levels, along with progress statistics, attempt averages, personal-best tracking, and speedrun records.

Players can launch balls using the left or right mouse button or the spacebar, and daily spins provide power-ups for difficult stages. Snails slow the core’s rotation, while hearts protect players from collisions. The game is free to play, with daily spins available without ads or registration. Coreball also offers a mobile app for iOS and Android, featuring 165 exclusive levels, online progress, and global leaderboards. Players can link their app account to the web game for a one-time welcome bonus and compare app rankings, while web and app progress otherwise remain separate.
