Infinite Minefield is exactly how it sounds: minesweeper on an infinite board.
The idea came from a mix of minesweeper.online and GRYKUBY's Infinite Minesweeper. As soon as you go on minesweeper.online, you can instantly start playing. GRYKUBY's Infinite Minesweeper is the main inspiration of an infinite minefield that you can come back to at any time. This website combines both; you open the page and you're already playing, and you have an infinite grid that saves your progress.
All of your hard work and progress is saved automatically in your browser. Close the tab, come back next week, or whenever you want — your entire explored map is still there, right where you left it. No account needed, no cloud, nothing to sign up for. It all lives locally on your machine. As long as you don't clear your browser cache, it's saved. You can also modify how much storage you want to allocate to your save, but the save is pretty optimized where each 32×32 chunk of tiles is typically under 1 KB (using binary RLE compression), which gives you plenty of space to play on before you even hit 5 MB.
And if you want to tune how the game feels, there's a lot to play with. You can adjust controls, keybinds, UI elements, and many other different options to tweak. I did my best to make it look visually faithful to Winmine while adding extra features to customize at your heart's content (scope creep is real).

An infinite minesweeper world that grows as you explore. Progress saves automatically — close anytime and come back later.
You can only reveal or flag cells that are touching tiles you've already explored. You can't click randomly into unexplored territory — the board expands outward from where you are. This is what makes the infinite world feel connected. You can turn it off in Quick Options below.
