Minesweeper

The classic you came for

Beginner 9×9 with 10 mines, Intermediate 16×16 with 40, Expert 16×30 with 99. Expert stands upright — a phone is held that way, and lying sideways the cells would be half a finger wide. Cells stay finger-sized and large boards pan.

100,000 numbered boards per size, the same on every phone. Before you open a cell, the header shows how hard the board is — Easy, Medium, Hard or Very hard — rated by the reasoning it needs, not its size.

Cells are drawn as the raised squares of classic Minesweeper. A cascade flows the way the empty cells connect, and every cell you open plays the next note of a scale, so steady play becomes a little melody.

Every world twists the rules

• Honeycomb — hexagon cells with six neighbours.
• Misty Woods — fog cells that show no number when opened.
• Desert — cross numbers that count only up, down, left and right.
• Ruins — coloured zones that tell you how many mines they hide.
• Snowfield — line counts along the edges.
• Ocean and Starry Night — the rules you've met, combined.

Each new rule is shown first on a tiny example board. Hold an open number on any board to see exactly which cells it counts.

Even with twisted rules, every board is guess-free. A number always says "this many mines among these cells"; a twist only changes which cells. There is one solver, tested against every possible arrangement for each rule.

Ten worlds, two hundred boards

Follow the winding path one board at a time. Each world brings one new thing — the first three teach a way of reasoning (one number, two numbers together, counting the mines left); after that, the rules themselves start to twist.

Three stars on each board — clear it, no hints or mistakes, beat the time. But stars never block your way: clear a board and the next one opens.

The first three boards of the Meadow are guided. The board points to your next move by itself, and a bubble above it says what to do and why.

Hints that explain why

Most hints just reveal a safe cell, and you're stuck again on the next board. Here, a hint points to the numbers that decide it and says in one sentence which reasoning it took.

Read these two numbers together. One of them must keep all its mines in the cells they share (shaded), so its other cells — outlined — are safe.

Every loss shows where you could have known

Step on a mine and the board is over — even if the numbers had already given it away. Then "Where?" shows the board just before your move, with a cell you could have known and why. It also tells you whether you guessed or the numbers had already shown the mine.

You can play on from just before the losing move; clear it that way for one star.
