About Focus Practice
Focus Practice strips the classic away from installers and launchers: open the page, click a square and the board generates itself around your opening move.
A single uninterrupted board is a surprisingly effective attention reset. The rules have not changed since the original. Every revealed square either opens into empty space or shows a number, and that number is the exact count of mines touching it across all eight neighbouring squares.
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.
