A shared-map puzzle platform
where everyone explores together
World Sweeper is a browser game where players build vast shared maps on top of real maps and images, gradually exploring them together. It offers multiple game modes on the same shared-map foundation: MineSweeper, ColorSweeper, Nikakudori, and MojiChat. Cooperative progress, light area competition, and a spectator-friendly sense of place come together as solved areas remain visible on the board itself.

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.
What is ColorSweeper?
It is a shared color puzzle where players claim an area and swap tiles back into the correct gradient. It uses the same persistent world structure while offering a clearly different play feel from Minesweeper.
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.
