About this game

A world within a circle—
Have you ever imagined a realm where every circle holds another universe?

Circleum is an idle game that begins in pure black and white,
and gradually fills with color as time passes.
Explore a fractal world of endless circles,
where fairies battle, grow, and unlock new layers of existence.

Features

◉ Fractal Worlds Within Circles
Each circle leads to another world, each with its own unique rules and mysteries.
As you explore, the universe expands endlessly in beautiful, repeating patterns.

◉ From Monochrome to Color
The game starts in stark black and white.
As you progress, color is gradually restored—
a visual representation of growth and discovery.

◉ Idle Fairy Battles
Fairies reside in every world.
They fight, evolve, and unlock new realms even while you’re away.
Just sit back and watch your world thrive.

◉ Elegant Silhouette Art
Minimalistic yet expressive visuals in black and white.
As colors return, the world transforms into something alive and breathtaking.

Restore color to a fading world.
Journey through every circle—
and uncover the final world beyond the fractal.

Begin your journey in Circleum now.
