Games may have more than one valid solution. It is debatable if this should be allowed to happen or not. However, at least the loadable game "Soccer" has also two solutions. I suppose this is undesirable. In other words: at least the solutions for loadable games should be unambiguous. Reproducible: Always

Sorry for the late reply, I was out of the country for a while. We did try to avoid having ambiguous solutions for the preset puzzles, looks like we must've missed one. Did you have a suggested fix for this particular one? I'm also fine with keeping this one as is since it's a minor difference and looks decent both ways.
(In reply to Jakob Gruber from comment #2) > Did you have a suggested fix for this particular one? After thinking about this for a while: how about filling the ball? I have not double checked it, but I suppose that the solution then becomes unambiguous.

Created attachment 126929 [details] Screenshot of "hourglass" with all but the ambiguous part solved Also the puzzle "hourglass" is ambiguous. I attach a screenshot with all but 8 fields solved. It is easy to see that the remaining 8 fields can be solved in 2 ways due to symmetry. I am not 100 % sure, but the solution would probably be unique if e.g. highlighted field was filled instead of blank.
#5: Thanks for reporting. Next time please file a new bug since this is a different (though similar) issue to the one reported 5 years ago ;)
