FullHex Autor: Justin Sawyer

Play colonist.io edge to edge.

Free colonist.io accounts reserve a 165px strip down each side of the board and a 90px strip along the bottom for ads. If you run an ad blocker, the ads are gone — but that reserved space just stays blank blue, shrinking your game board for no reason.

FullHex tells colonist to collapse those gutters and re-lay-out the board at full size, so the hex map fills your window instead of floating in a frame of empty space.

What it does
- Removes the blank left, right, and bottom ad gutters in-game
- Resizes the board to use the full browser window
- Kicks in automatically the moment you open a colonist.io game

Lightweight and private by design
- No ads, no analytics, no tracking — nothing is collected or sent anywhere
- No account, login, or configuration
- No background process and no toolbar UI
- Runs only on colonist.io and touches nothing else you browse

Good to know
- On the very first frame you may see the gutters flash for a fraction of a second before the board expands — that's expected.
- The in-game fullscreen toggle (the little expand icon) will think it's already fullscreen, so it won't trigger browser fullscreen. The board is already filling the window, so this is purely cosmetic — and F11 still works for true browser fullscreen.
- If a colonist.io game doesn't resize, reload the tab after installing.
