Here's a fun grid puzzle. The rules are simple: just determine which squares should be filled in with an X. Each square contains a number in its upper right corner. That number dictates how many X'd squares are adjacent to that one. For example, a square with a 3 in it would indicate that three of the squares around it should have an X in them. You just have to figure out which 3 squares. I put a dot in squares I know should NOT contain X's.

The highest number that can appear in a square is a 4, though there aren't any in this particular puzzle. But if there was a square marked with a four that would mean that all four squares directly around it would contain an X. Squares diagonally aligned are irrelevant.

Thank you for that brilliant and completely off-target deduction!

Minesweeper is a different game with different objectives. Similarities? yes, so possibly anybody who enjoys Minesweeper might enjoy this grid puzzle. Or anybody who likes traditional logic without the speed, stress or memory factors of Minesweeper. I personally prefer laid-back puzzles that I have to think hard to solve but that I can take my time with.

I will see what I can do about the link.

Alright, I take it back: this is much better than minesweeper. Thank you.

I almost finished the mega-puzzle. But my eyes are bleeding and I have to get up early tomorrow, so I must force myself to stop (for now).

Okay, I don't think eSnips is a good image server. I have reuploaded the grid puzzle to a different server. Sorry for the inconvenience. Hopefully this will work better.
