                Anonymine is the "anonymous minesweeper" as I never had any

                name for it, but I think "Anonymine" works just fine.

                Back in December 2015 I was curious about creating an algorithm

                for solving minesweeper, and then I needed an excuse for it

                so I turned it into a terminal game that can be solved wihout any

```
                guessing.
```
```
            </p>
```
```
            <p>
```

                Do note that it runs in the terminal, so it may not be your cup of

                tea.  Mouse input is usually supported, but only really useful in

```
                hexagonal mode.
```
```
            </p>
```
```
            <p>
```

                Being solvable without guessing is not its only feature,

                it has many other unusual or even unique features:

                the games are fully customizable and Anonymine seems to be the

                only minesweeper with <span class="a"><a

                href="https://en.wikipedia.org/wiki/Von_Neumann_neighborhood"

                >von Neumann grids</a>.</span>

                <!-- No printurl, it's just Wikipedia. -->

```
            </p>
```
```
            <p>
```

                For each game you can set the field type (normal / hexagonal

                / von Neumann), width, height and number of mines, only

                restricted to certain minimums and security limits (to avoid

                igniting your computer).

```
            </p>
```
```
            <div class="atom">
```

            <h3>The supported field types/game types are:</h3>

```
            <div class="atom">
```

            <!-- FIXME: This should be a dl with dt and dd. -->

```
            <h4>Von Neumann grids</h4>
```
```
                <p>
```

                    I have never seen another

                    minesweeper that can have fields with von Neumann

                    grids.  In a von Neumann neighbourhood (grid),

                    each cell/square has only four neighbours, at the edges

                    but not at the corners.

```
                </p>
```
```
                <p>
```

                    The biggest number you'll ever see is 3. But that doesn't

                    mean it's easy, it's quite the opposite.

```

```

                    Every cell is a hexagon and has six

                    neighbours, (with obvious exceptions).

                    This mode has separate key bindings because there is no

                    single "up" and single "down" direction.

                <pre>0.6.32
```

    - enginecfg update: more fine grained control of highscores.

```
      It SHOULD be backward compatible.
```
```
0.6.22
```
```
    - check-install-cfg is smarter now
```

    - If you have modified cursescfg you may want to check what updates 0.6.20

      brought, previously check-install-cfg would have FORCED you to update.

0.6.20 (BROKEN for new installs, fixed in 0.6.21)

    - Significant changes in cursescfg.  Old configuration file is still

      compatible, but most changes of this release is in that configuration

```
      file.
```

    - check-install-cfg can't properly check compatibility, run

        ./configure skip-check-install-cfg=true

      if you want to keep the old cursescfg and assume it works.

```
0.6.19
```
```
    - Fix issue 32 and 33
```

    - Fix 33 will prevent you from setting ONLY the -c option when used

      over an SSH connection. Simply add another option or run

      `SSH_CLIENT= anonymine -c path/to/cursescfg`

    - From now on, configuration files MUST NOT be modifiable by group members

```
      even if group ID is zero.</pre>

```
================================
```
```
2024-xx-xx
```
```
Improved platform support:
```

    - SerenityOS (0.6.26, improved 0.6.31)

    - Icon for Anonymine on Haiku (0.6.17)

    - Fixed a race condition that previosuly required a bunch of platform

```
      specific workarounds (0.6.11)
```

    - Use Notepad to display highscores on Windows (0.6.33)

```
Updates:
```

    - New, much faster, field initialization algorithm. (0.6.29)

    - Reproducible fields using seeds (0.6.32)

    - Fixed race condition (fix14) (0.6.11)

```
Security fixes:
```

    - 0.6.19: Prevent information leak if Anonymine is used as login shell

```
              for ssh.
```

    - 0.6.32: Prevent local DoS.  Don't read the entire highscores file,

              which is writeable by everyone, if it's too big.

    - 0.6.34: Check file permissions before loading configuration files</pre>
