90-Second Minesweeper
Flag all 20 hidden mines on a 10x10 minefield before the 90-second clock runs out in this fast, free Minesweeper game in your browser.
About 90-Second Minesweeper
90-Second Minesweeper takes the classic logic puzzle and adds a ticking clock. The 10x10 board hides 20 mines, and every number you uncover tells you how many of them touch that square. Read the clues, mark each mine with a flag and do it all in a minute and a half.
The pressure changes how you play. There is no time to overthink every corner, so you learn to spot safe patterns quickly and trust your deductions. Uncover a mine or let the timer hit 90 and the game ends, showing where every bomb was hidden. A little emoji face reacts to each move, from nervous to cool when you win.
It is a great quick challenge for Minesweeper fans and anyone who enjoys short, tense logic puzzles.
How to play
Reveal squares to uncover numbers that show how many mines touch that square; empty areas open up automatically. Mark every mine with a flag: you win when all 20 mines are flagged. Revealing a mine or running out of the 90 seconds ends the game, and the face button starts a new board.
Controls
- Click / Tap
- Reveal a square
- Right-click / Long-press
- Place or remove a flag
- Face button

Tips
- Start by clicking near the middle: a square with no mines around it opens a big area at once.
- A 1 touching only one hidden square means that square is a mine, so flag it right away.
- The flag counter shows how many mines are left to find, and you only have 20 flags.
- Do not waste seconds on a pure guess early on; solve the obvious squares first.
