Lantern fog of war for your battle map
No player window Unlock Pro Settings

Hide the map. Reveal it room by room.

Drop a battle map here or pick one. Your players see only what you reveal, in a second window on your TV or projector.

Your first map is free. Images stay in this browser and are never uploaded.

Fog

Player window

Open it, drag it to your TV or second monitor, then press Fullscreen there. It shows only what you reveal and updates as you draw.

It must run in this same browser on this same device. Players joining over the internet are not supported. If nothing opens, allow pop-ups for this site.

Grid Pro

Tokens Pro

Tap the map to place a token, drag to move it. Players see a token only where the map is revealed.

Maps

The current map and fog are kept in this browser, so a reload picks up where you left off.

    FAQ

    What does £6.00 buy?

    One payment, no subscription, no account. It unlocks unlimited maps, the saved maps library with export and import, the square grid and tokens in this browser. Your first map is free to try.

    Where are my maps kept?

    Only in this browser. Map images and fog never leave your device. The only things sent to our server are a page-view count and, if you pay, the Stripe payment check.

    Which browsers work?

    Built and tested in current Chrome and Edge; recent Firefox and Safari should work too. The player window must run in the same browser on the same device, so allow pop-ups for this site.

    Can I get a refund?

    Access starts straight away, so the 14-day cancellation right ends once you use it. If something does not work for you, email business@thatched.ai and we will look at it.
