Play Minesweeper in your browser on the classic Beginner, Intermediate and Expert boards, a daily board and a custom size. The first click always opens an empty area, and smaller boards can be solved without guessing. No app, no sign-up and nothing to dismiss before you play; it works offline and every cell can be opened or flagged from the keyboard.
Minesweeper board is loading.
Almost every Minesweeper board is solved by a handful of small deductions repeated many times. Learn to see them at a glance and you will spend your time moving, not staring.
Look for a number that touches exactly as many hidden cells as its value: they are all mines. Then look for a number whose mines are all flagged: its other hidden neighbours are all safe. A 1 in a corner of the open area touching a single hidden cell is the classic example. These two rules alone clear most of a Beginner board.
Along a straight wall of hidden cells, the row 1-2-1 always means the mines sit opposite the two 1s and the cell opposite the 2 is safe. The row 1-2-2-1 means the mines sit opposite the two 2s and the cells opposite the 1s are safe. Both follow from comparing neighbouring numbers, but recognising the shape saves the working out. They turn up constantly on Intermediate and Expert.
When two numbers share some hidden cells, subtract. If a 1 touches cells A and B, and a 2 next to it touches A, B and C, then C must be a mine, because the 1 can supply at most one of the 2's mines. If both numbers were 1, C would be safe. This subset idea is what the hint calls Subset, and it is the step that lifts most players from Beginner to Expert.
Once a number has all its flags, click it to open its remaining neighbours in one move. Chording is only as safe as your flags, so flag what you have proven, not what you suspect. Good Expert times come from flagging and chording in one smooth pass along the edge of the open area.
Near the end, the mine counter is a clue. If three mines are left and a pocket of hidden cells can only hold three, every other hidden cell is safe. When nothing can be proven, guess early rather than late, and pick the cell whose opening tells you most: a cell away from the frontier often has lower odds of a mine than a true 50/50 on the edge, and it can open a fresh area.
Beginner is 9×9 with 10 mines, Intermediate 16×16 with 40, and Expert 30 columns by 16 rows with 99. Custom lets you choose from 5 to 30 rows, 5 to 40 columns and up to a third of the cells as mines.
Mines are placed after your first click and never on that cell or its eight neighbours, so the first cell always shows 0. With the No-guess boards setting on, which is the default for boards up to 256 cells (Beginner, Intermediate and small custom boards), the game picks a layout its built-in solver can clear from that opening using single-number, subset and mine-count logic. You can switch it on for all levels or off in Settings.
Games about finding hidden mines on a grid go back to the mainframe and home-computer era of the 1980s, when several similar programs appeared. The version most people remember became widely known in the early 1990s, when a Minesweeper-style game was bundled with personal computers and turned into one of the most played puzzles of its time.
The three standard sizes, 9×9 with 10 mines, 16×16 with 40 and 30×16 with 99, have stayed the common reference ever since, and players still compare Expert times on them.
The hub plays Beginner. The daily is an Expert board generated from the date, the same for everyone in the world, with a new one at midnight UTC.
The timer starts on your first move and pauses when you switch tabs. Stats per board size stay in this browser: played, won, win rate, best and average time, and your daily streak.
Undo and Redo cover the whole game, even the first click. The first two hints on a puzzle are free; if ads are switched on later, more hints offer a short ad or a 30-second wait. Wins come with share text, and every random board has a code such as A7K3Q that replays it.
Minesweeper boards scroll and zoom inside the frame on a phone, and every cell can be opened or flagged from the keyboard. Tidy Puzzles runs entirely in your browser: there is no app to install, no account to create and no interstitial before you can play. After the first visit the game also works offline, because each puzzle is generated on your device from a seed. Every board can be played with the keyboard alone, on a phone or a desktop, and your stats and unfinished puzzles stay in this browser rather than on a server.
Open cells one at a time. Each number tells you how many mines touch that cell. Use the numbers to work out which cells are safe and which hold mines, flag the mines, and open every safe cell to win.
Yes. Mines are placed only after your first click and never on that cell or its neighbours, so the first click always opens an empty area.
Clicking an open number that already has as many flags around it as its value. All its other hidden neighbours open at once. If one of the flags is wrong, the chord opens a mine.
Along a straight edge, a 1-2-1 row means the mines are opposite the two 1s and the cell opposite the 2 is safe. In a 1-2-2-1 row the mines are opposite the two 2s.
Not in general. Here, Beginner and Intermediate boards are chosen so they can be cleared by logic from the first opening, and you can turn the same option on for Expert. Plain random boards sometimes need a guess.
Long-press the cell for about half a second, or switch on Flag mode under the board so a normal tap places a flag.
Expert has 99 mines on a 30 by 16 board, about one cell in five. Intermediate has 40 on 16×16 and Beginner 10 on 9×9.
Yes. Arrow keys move between cells, Enter or Space opens a cell or chords a number, F places a flag, and H asks for a hint.
9×9 with 10 mines, always solvable without guessing by default.
16×16 with 40 mines, where the 1-2-1 pattern starts to matter.
30×16 with 99 mines, the board for serious times.
One Expert board a day, the same for everyone, with a streak.
Choose rows, columns and mine count for your own board.
Picture logic grids, always solvable by line logic alone.
Unique-solution grids from Easy to Evil with technique hints.
