Mini Mine Sweeper
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

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.
