Sapper: No-Guess Minesweeper

Minesweeper the way it should be: every board can be solved by logic alone — no 50/50s, ever — and every board is rated by the thinking it needs, not just its size. Square, hex, triangle, knight and torus boards. Size and density as separate dials. Chording, an adjustable long-press, a flag toggle. 3BV and 3BV/s on every result. A daily board that is the same for everyone. A 1,200-board ladder. Your history, forever. No ads. Ever.

No guessing

Every board in No-guess mode is checked by a solver before you see it: from your first tap to the last cell there is always a safe deduction. The same solver rates the board by the hardest technique it needs — Gentle, Standard, Sharp or Fierce — so "hard" means harder thinking on the same grid, not just more mines. Classic minesweeper, with guessing, is there for purists and says so.

Controls that respect your thumb

A long-press that has placed a flag can never fire a reveal when you lift. Tap a satisfied number to open its neighbours. Swap tap and hold, tune the hold from 150 to 600 ms and test it right in the setting, or use the big flag toggle. Pinch to zoom, pan with one finger.

Five board shapes

Square, the classic. Hex, six neighbours and a board that looks like nothing else. Triangle, twelve neighbours, for experts. Knight, where a number counts the mines a knight's move away. Torus, where the edges wrap and there is no safe corner.

Your dials

Beginner, Intermediate and Expert — the three minesweeper presets everyone knows — on every shape, and a Custom card with width, height and density as separate sliders, shown as a percentage and a mine count.

Numbers you can trust

Time to a tenth, 3BV and 3BV/s on every result card — the minesweeper community's own measures, not a black-box score. Personal bests per preset with the delta on every win. A history of every game, never truncated, and a backup file that merges without ever lowering a best.

A daily board and a ladder

One minesweeper board a day, the same for everyone, built on your phone from the date — offline, no server, no signal needed — with a streak and freezes. A ladder of forty chapters, thirty boards each, rated from all-Gentle to Fierce, with stars for a clean solve.

Hints that teach

A hint shows the numbers that prove the next move, not just the answer. In Classic, when nothing can be deduced, the hint says so: "this is a guess" — the most useful thing a minesweeper can tell you.

Made to be looked at

Flat, fast and vector-drawn, with the polish in the motion: a flood that ripples out from your tap, a flag that pops, a win that settles. Slate, OLED and Paper themes free; a hand-drawn Retro theme and an Ink theme in the unlock. Colour-blind numbers, reduce motion, a left-handed tray, and a board a screen reader reads cell by cell. Twenty-two languages.

No ads. Ever.

No banners, no interstitials, no rewarded videos, no consent forms, and no advertising SDK in the app at all.
