Corona Sweeper is a casual puzzle game that cleverly re-themes the classic Minesweeper experience. In this browser-based logic challenge, your goal is to locate and quarantine all the sick people on a grid without accidentally revealing any.
Using simple mouse clicks, you'll clear the board based on numerical clues indicating adjacent threats.
The core of Corona Sweeper is identical to the logic puzzle game it's based on. You start with a grid of covered squares. Clicking a square will either reveal a sick person, ending the game, or it will show a number.
This number tells you exactly how many infected individuals are in the eight squares immediately surrounding it.
If you click a square that has no sick neighbors, it will be blank, and the game will automatically clear all adjacent blank squares for you.
Your mission is to use these numerical clues to deduce which squares are safe and which ones are hiding a sick person. It's a game of pure logic and deduction.
When you've deduced that a square contains a sick person, you shouldn't click on it. Instead, you can right-click (or long-press on touch devices) to place a flag, effectively quarantining that spot. This serves as a visual reminder to yourself not to click there.
Correctly flagging all the sick people is crucial for clearing the remaining safe squares and winning the game.
Using flags helps you manage the board and avoid making mistakes. As you place more flags, you can use the surrounding numbers to confirm other squares are safe.
For example, if a square shows a '1' and you've already flagged the only adjacent square, you know all the other neighbors are safe to click. This process of elimination is key to success in Corona Sweeper.
You can enjoy Corona Sweeper directly in your web browser with no downloads required. Because it's a simple HTML5 game, it runs smoothly on most devices, including Chromebooks and PCs on school or work networks.

Your objective is to clear the entire grid by revealing all the squares that do not contain sick people. Use logic and the numerical clues provided to avoid clicking on any infected squares.
Use your mouse to interact with the game. Left click on a square to reveal what's underneath it. If you suspect a square contains a sick person, use a right click to plant a flag on it as a warning.
On touch devices, a simple tap reveals a square, while a long press will place a flag.
When you reveal a square, it might show a number. This number indicates how many sick people are in the eight adjacent squares (horizontally, vertically, and diagonally).
If you reveal a blank square, it means there are no sick people nearby, and the game will automatically clear all connected blank squares for you.
You win the game when all safe squares have been revealed. The game ends immediately if you click on a square containing a sick person.
Start at the Corners - The corners of the board only have three adjacent squares, making it easier to deduce what's safe early in the game. Prioritize '1's - A square with a '1' is your most useful clue.
Once you identify the single infected neighbor, you know the rest are safe to clear.
Clear in Groups - Clicking a blank square (one with no infected neighbors) is a huge advantage, as it clears a large area and gives you lots of new numbers to work with. Flag with Certainty - Avoid guessing.
Only place a flag when you are 100% sure a sick person is there. A wrong flag can confuse your later deductions.
Use the Chord Technique - If a numbered square already has the correct number of flags next to it, you can left-click it again to automatically reveal all other non-flagged neighbors.
Look for Patterns - Recognizable patterns, like a 1-2-1 sequence, often have standard, safe solutions. Learning these can speed up your clearing time.
