M-x eval-buffer M-x puzzlemacsI have tested the game using Emacs 22 and Emacs 23 without any issues.
Scoring is not completely standardized yet. You may generate a different amount of keypresses when running in a terminal and when running in a windowed environment. Keep this in mind if you want to compare your scores to others. (I'm running it in a windowed environment.)
Personally I also consider the game to be more fun and challenging if you are not allowed to use the mouse to position the cursor. (Even if using the mouse would allow you to minimize the number of keypresses.)
Also, it is of course quite easy to cheat. For example, just prerecord a macro that solves the problem. There is not really a good way to detect this in emacs so I have not even tried to do this. However, I do record the exact keypresses used in the highscore file. As yet this isn't used in any way, but it could be used for verifying that a solution is not using any doubtful approaches in a future version.
