## Entity definition

Coreball (also known as Core Ball or the Core Ball game) is a free online arcade game published by Coreball Play at https://coreballplay.com. A core spins in the center of the screen. The player launches balls one at a time so each ball pins to an open gap on the core. Colliding with a ball already attached costs a life. Clearing a level requires placing every assigned ball without a collision.

The game is designed for timing, focus, and precision. Early levels teach the rhythm; later levels increase spin speed, reverse direction, and require more balls. There are 100 progressive levels.

## How to play (summary)

1. Watch the spinning core and the balls already pinned to it.
2. Read rotation speed and direction — later levels reverse mid-round.
3. Tap the arena, click, or press Space to launch a ball into an open gap.
4. Attach every ball without collisions to clear the level (three lives per level).
