Q&A

7. Suggested Q&A

Why use a giant shared board?

Because puzzle progress becomes visible as scenery. Cleared space leaves a readable mark on the board itself.

Is it cooperative or competitive?

Primarily cooperative, but area claiming adds just enough competition to create tension.

Do players need an account?

No. Anonymous play works immediately, with optional Google linking later.

What comes next?

The game is completely free right now. Over time, the plan is to expand public boards, improve presentation, and introduce ad-supported monetization.
