Blot Sweeper
The classic number-logic puzzle, with ink blots hiding under the paper instead of anything scary. Tap a square to uncover it. Numbers tell you how many blots are touching that square, so you can work out where they are, flag them, and uncover every clean square to win.
- Puzzle
- Your first tap is always safe
- Easy, Medium and Hard
- Saves your best on each level
How to play
- Pick a level. Easy is 8×8 with 10 blots, Medium is 9×11 with 18, and Hard is 10×13 with 30.
- Tap any square to start. Your first tap is always safe and opens up part of the page.
- Each number shows how many ink blots touch that square, including diagonally.
- Mark squares you know are blots with a flag: switch to Flag, or press and hold a square.
- Uncover every clean square to win. Uncover a blot and the page is ruined.
Controls
- Tap a square to uncover it.
- Switch to 🚩 Flag, press and hold, or right-click to put a flag on a square.
- Tap a number when all its blots are flagged to uncover everything around it at once.
- The Sound button turns sound on or off.
Tips
- Start with the 1s next to corners. They often point to exactly one blot.
- If a 1 touches only one covered square, that square is a blot. Flag it!
- If a number already has all its blots flagged, every other square around it is safe.
- Look for the 1-2-1 pattern along an edge: the blots sit under the two 1s.
About Blot Sweeper
Blot Sweeper is our take on minesweeper, the logic puzzle that came with computers for years. We swapped the bombs for ink blots, because a notebook doesn't explode, it just gets messy.
Every page is random, and your first tap is always safe, so you never lose on a lucky guess.
