What are the basic rules of Star Battle Online?

In Star Battle Online, you must place exactly two stars in every row, every column, and every outlined region on the grid. The critical rule is that no two stars may touch each other, including diagonally. This means each star blocks itself and the eight surrounding cells from containing another star. The puzzle is solved when all rows, columns, and regions contain their required two stars, and no stars violate the no-touching rule.

How do I get started if I have never played Star Battle before?

Start with Level 1 in the progressive level system, which introduces the core mechanics on a small, manageable grid. Use the "Learn the Rules" section and strategy tips provided on the platform. Begin by scanning each region for areas with only two or three possible cells, then compare those cells against their rows and columns. Use the X-marking tool to eliminate impossible cells, and only place a star when the same cell satisfies every rule simultaneously.

Is there a way to save my progress in StarBattle Online?

Yes, StarBattle Online offers optional progress saving when you set up a site-specific account. This allows you to track which levels you have completed, resume puzzles you started earlier, and maintain your daily puzzle streak. Creating an account is straightforward and ensures that your solving history and achievements are preserved across different browsing sessions and devices.
