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.

Your next move

Choose your game variant, line up blocks, and beat your best score.

Clear exactly three consecutive numbers in a horizontal or vertical line whose sum is zero. Integers only: Easy ±1–5, Normal ±1–7, Hard ±1–9.

Line up blocks of the same color horizontally or vertically: at least 3 on Easy, 4 on Normal, or 5 on Hard.

Fill every playable cell in a row. Beside the central zero, either half can clear.

Start with an empty board. Clear blocks to level up as the game gets faster.

Clear every gold-outlined target to finish the level. Targets stay in place until cleared.

Start with one marked block. Another appears every 8 blocks cleared, or 5 rows in Rows.
