I'm wondering if the same concept would work with a hex grid, and numbers 0-6.

Here are two more number grids. The first one is easier. The second one I found more difficult to solve.

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.

I don't know what these puzzles are actually called but I like them a lot better than Sudoku. Similar thinking -- a nice, leisurely puzzle -- but less wearying, somehow. Hope you enjoy!
