The world of Zeronia

On the distant planet Zeronia, everything exists in balance. Energy, matter and logic follow a single rule: zero.

Then the balance breaks. Random numbers, colors and blocks begin to fall, pushing Zeronia toward chaos.

You are the 0 Hero, a guardian of balance in a world ruled by numbers. Each cleared pattern creates space and restores a little harmony.

As long as randomness exists, Zeronia needs a defender. Practice in Arcade, or meet another Hero in the Arena.

Balance is simple. Mastery is not.
