NÚCLEO

Spin the planet. Complete the rings.

In NÚCLEO, pieces don't fall down a well — they fall toward the core of a planet. Instead of moving the piece, you spin the whole world beneath it. Close a full ring and it vanishes; everything outside collapses inward.

One simple rule. No walls. A board that wraps all the way around.
Easy to learn in seconds. Hard to put down.
