Classic Minesweeper recreated in Scratch with 40 hidden mines. Click to reveal, press Space to flag, and keep your score (top-right timer) low.


A faithful Minesweeper made in Scratch: every board hides 40 mines, the score is a timer, and flags are placed with Space. No downloads, just press the green flag to start.
Run entirely in Scratch—click the green flag to begin, stop button to reset. No installation needed.
Numbers show how many mines touch a tile (including diagonals), matching classic Windows rules.
Each round uses 40 hidden mines, keeping density consistent from start to finish.
Top-right timer is your score; faster clears mean better runs.
Core rules for this Scratch Minesweeper build.
You win by revealing every non-mine tile. Any mine click ends the run.
Each number counts adjacent mines (8 surrounding tiles). Use them to decide which tiles are safe.
Hover a covered tile and press Space to toggle a flag when you are sure a mine is there.
If you hit a mine, click the stop button then the green flag to generate a fresh board.
Practical, non-spoiler tips that come straight from classic Minesweeper play.
Common shapes like 1-2-1 or 1-1 along edges often force exact mine placements.
Only flag when adjacent numbers demand it; avoid guessing early.
Empty tiles fan out safe openings—use them to expose large areas quickly.
Count remaining mines versus unopened tiles in each region to pick the safer guess.
