How to play WorldSweeper
WorldSweeper turns the world map into a cooperative Minesweeper board. Choose a safe Home Base, read the numbers, mark suspected mines, and reveal the same living world alongside other players.

Is the board private or classic?
No. Players in a world do not get separate private or classic boards. Everyone sees one geographic board whose shared state is authoritative on the server.
How does a player start?
Browse the public world catalog before signing in, then sign in to enter or create a world. Pick a requested Home Base cell on the minimap (or use a continent or device-location quick choice), confirm the server's safe result, then select a legal adjacent hidden land cell and choose Open or Flag.
Is WorldSweeper competitive?
No. The current game has no PvP combat, stealing, or score-race competition. A selected world has an interactive territory score rail for current owned cells, including automatically claimed mines. Select a player to jump to their Home Base; it is not a public title ranking.
Quick start
From the title map to your first reveal
There is no separate level grid. Every playable land cell belongs to the same geographic board, and every successful action changes that shared world.
-
Choose a world
Browse the public world list. Sign in when you are ready to enter an existing world or create one when no empty world is waiting.
-
Set your Home Base
New players pick a requested land cell on the minimap and confirm the authoritative safe result. The server opens a starting area of up to 7×7, with up to 49 safe land cells. Continent and device-location choices remain available as quick starts.
-
Explore the map
Drag to pan. Use the mouse wheel or a two-finger pinch to zoom. Open the minimap whenever you need a wider view of the world.
-
Choose a cell action
Select a legal hidden land cell to open its radial menu, then choose Open, Flag, Question, or Unflag. Water is terrain and cannot be opened.
Core rules
Classic clues, shared consequences
The familiar Minesweeper logic still applies, but ownership, flags, and mine hits are synchronized for everyone in the same world.
Read the numbers
A revealed number tells you how many mines touch that cell. Combine nearby clues to decide which hidden land cells are safe.
Mark suspected mines
A flag blocks that cell from being opened. Flags are shared with the world, and only the player who placed a flag can remove it. A question mark is your private browser note and never blocks another player.
Claim a proved mine
When the opened numbers prove your flagged cell is a mine, the game automatically clears the flag and claims that visible mine as territory. Unproved flags remain flags.
Recover from a mine
Hitting a mine resets the affected blast area to hidden, unowned, and unflagged. The hit cell is rerolled safe, so no visible mine remains permanently.

Play together
How to play WorldSweeper with friends
-
Invite from your world
Enter a world and use Invite to share your current world and Home Base coordinate. Use the operating system's share sheet, or send the copied link when sharing is unavailable.
-
Open the link and sign in
Your friend opens the invitation and signs in with their own account. The link selects the invited world; it does not share your account.
-
Join or return
A new member sees the Home Base picker with the invited coordinate preselected and may choose another location. Confirm the server's safe placement, which may move to nearby safe land when the requested cell is unavailable. An existing member keeps their progress and Home Base; the camera moves to the invite coordinate.
Everyone in the same world shares its board state in real time. Each account's progress is kept independently for every world it joins.
Common questions
Before you enter
Is WorldSweeper competitive?
No. The current game has no PvP combat, stealing, or score-race competition. The selected world's score rail shows territory and lets you jump to a player's Home Base. It is not a public title ranking; players reveal and map the same world cooperatively.
Does each player get a private board?
No. Players in a world see the same authoritative board. Safe reveals, flags, ownership, and blast resets are shared in real time.
Do I need an account?
You can browse the public world catalog before signing in. An account is required to enter a world, choose a Home Base, and make shared moves.
What happens when I return?
Continue reloads the current shared state and returns the camera to your Home Base in that world. Your progress is kept independently for every world you join.
