Clean Sweep

No guessing. Pure logic.

Frequently asked questions

How do I play?

Tap a tile to open it. A number tells you how many of the eight surrounding tiles hide a mine. Long-press a tile — or switch on the ⚑ button at the bottom — to place a flag. Tap a number whose flags are all placed to open every remaining tile around it at once.

What does “no guessing” mean?

Every board is checked before you see it: from your first tap, it can be solved by logic alone. You will never reach a point where the only way forward is a coin flip.

What is the Daily Board?

One board per day, the same for everyone. It is played without undo, so times are comparable. Finish it on consecutive days to build your streak.

Is Clean Sweep free? What about the ads?

Yes, it is free and supported by ads. After you hit a mine you can choose to watch a short ad to undo that move — once per board, never on the Daily Board. Watching is always optional.

Why didn’t a board count toward my records?

Boards finished after using undo are counted separately and never affect your best times or streaks, so your records always reflect clean play.

I lost my statistics.
