Minesweeper

Every number counts the crystals touching that square. Work out where they are, flag what you can prove, and open the rest — the whole board falls to patience, not luck.

Your first tap is always safe — the board is laid out around it.

Right-click flags a square. Click a number to open around it, or press the middle button.

Or hold a finger on any square to flag it, wherever you are.

How to play

The numbers are counts
A number says how many crystals touch that square, counting all eight neighbours. A blank square touches none, so everything around it opens at once.
Dig and flag
Open a square you think is safe. Flag a square you can prove holds a crystal, so you do not dig there by accident. Flag the square again to take the flag back.
Open around a number
Once the flags around a number match it exactly, tap the number itself to open every other square around it in one go. Nothing happens until the count adds up.
Work it out, do not guess
On a no-guess board there is always a square that follows from the numbers you have already opened — no guessing required, right to the last square. Play Classic when you would rather take your chances.
On a phone
Pick Dig or Flag first, then tap. Holding a finger on a square flags it. On the big board, tap Zoom in and drag to move around; row and column position is easy to lose, so switch to Move when you only want to look.

About these boards: No-guess boards are not random boards that happened to look solvable. Each one is laid out square by square, following the same two rules a player would use, so a solver can always reach the end from your first tap. If a board cannot be built that way it is thrown away and redrawn, which is why a board may take a moment to appear.

Three board sizes: 9×9 with 10 crystals, 16×16 with 40, and 30×16 with 99
Your first tap and the eight squares around it are always clear
