5 total bombs in 3 by 4 grid (3 rows, 4 columns):

row 1: ? ? 2 1

row 2: 3 ? ? ?

row 3: ? 1 ? ?

Find the bombs.

Mine Sweeper rules: each number represents the exact total of surrounding mines.

row 1: ? ? 2 1

row 2: 3 ? ? ?

row 3: ? 1 ? ?

Find the bombs.

Mine Sweeper rules: each number represents the exact total of surrounding mines.

### Hint

There is enough information to figure out the entire grid.### Answer

* are bombs.row 1: * * 2 1

row 2: 3 3 3 *

row 3: * 1 2 *

Explanation:

Let's rewrite the grid with letters:

row 1: A B 2 1

row 2: 3 C D E

row 3: F 1 G H

Step 1: we know either D or E is a bomb (but not both).

Step 2: From Step 1, we know B or C is a bomb (but not both).

Step 3: From Step 2, we know A and F are bombs.

row 1: * B 2 1

row 2: 3 C D E

row 3: * 1 G H

Step 4: From Step 3, we know C, D, and G are not bombs.

row 1: * B 2 1

row 2: 3 - - E

row 3: * 1 - H

Step 5: From step 4, we know B is a bomb and E is a bomb.

row 1: * * 2 1

row 2: 3 - - *

row 3: * 1 - H

Step 6: Since there are exactly 5 bombs H must be a bomb.

row 1: * * 2 1

row 2: 3 - - *

row 3: * 1 - *

@ smurky :That is wrong, the two has three on it

@teaser: I loved it, I love to see a series

I got it by guessing and checking... I guess smurfy's first, but noticed the three bombs around the 2 so I changed it to the correct form.

Easy but fun to do.

I play Minesweeper all the time so I'm pretty good at it.

not hard but it is cool indeed

Great Teaser! I love Mindsweeper!

what abou this:

row 1: * * 2 1

row 2: 3 2 2 *

row 3: * 1 1 1

row 1: * * 2 1

row 2: 3 2 2 *

row 3: * 1 1 1

only four mines, sishu

dishu, i mean. typo, you understand.

i had a different route of solving:

A B 2 1

3 C D E

F 1 G H

Because of the 1 on the bottom, C and F cannot both be mines, because the 1 should then be a 2. It follows that both A and B are mines, because C and F have only one mine between them, leaving only two spaces for the remaining two mines (that surround the 3).

Therefore:

* * 2 1

3 C D E

F 1 G H

If C is a mine, then D and E are not mines because the 2 already has two mines neighboring it. But that means that the 1 in the upper right has no possible neighboring mine. This means that F is a mine, which leads to C, D, and G not being mines. E should be a mine for the 2 and the 1, and H is a mine as well, because there are exactly 5 mines. This corresponds to the solution:

* * 2 1

3 3 3 *

* 1 2 *

A B 2 1

3 C D E

F 1 G H

Because of the 1 on the bottom, C and F cannot both be mines, because the 1 should then be a 2. It follows that both A and B are mines, because C and F have only one mine between them, leaving only two spaces for the remaining two mines (that surround the 3).

Therefore:

* * 2 1

3 C D E

F 1 G H

3 3 3 *

I love MineSweeper so this was a piece of cake for me!

Thanks for a fun teaser!

Thanks for a fun teaser!

Great quick little puzzle. My only complaints are the "not a hint" and the needlessly long and confusing answer.
