About Flagless Speed Run
If you came looking for flagless speed run, this is the full game: a 256-square board, 40 buried mines and a timer that starts the moment you dig.
Flagless running trades safety for raw speed and is how most record times are set. Each number on the board is a promise. It tells you precisely how many of the eight squares around it hide a mine, and from that single fact whole regions can be solved without any luck at all.
Controls are deliberately small in number: left-click to reveal, right-click to flag, or use the on-screen mode toggle if you are playing on a touchscreen. The mine counter and timer update live as you play.
Your very first click is always safe. The mine layout is generated after you dig, and the algorithm keeps your opening square and its immediate neighbours clear, so no session ever ends before it has properly begun. Under the hood it is plain modern web technology: React for state, Tailwind for the neon styling, and oscillator-based Web Audio for the ticks, flag clicks, win chime and explosion. There is no plugin, no installer and no account.
There is no score to chase but your own time, which is exactly why the game has outlived the hardware it was written for. Whether you are here for a quick distraction or a serious attempt at a personal best, the board is ready the moment the page finishes loading, and it costs nothing to try again.
