So for the record, is both colours allowed to be moved? And does both or only one king need to reach the other side?

@Adam For one, please use proper grammar. And there kings stay where they are throughout the entire game, based on how the diagram looks. I’m already working on how to find even just one way to reach this position. I’ve already gotten some progress.

@Adam - This is calledRetrograde analysis
, and the standard constraint is that you are supposed to figure out how the position was arrived at via the normal rules of Chess - that is, alternating white and black moves, with white moving first, no unannounced checks, no failures to escape check, no illegal moves, and so on.

@RewanDemontay Why? That comment was unnecessary... telling someone to use "proper grammar" is quite an obnoxious statement. In general, grammar police-ing isn't necessary unless the grammar is so bad that the comment becomes unreadble. If it ever gets to that point, you can ask politely for that person to clarify rather than outright telling them that they have a bad grammar: Not only does that not fix any problems, but also creates conflict. We try to avoid that here. :)

So for the record, is both colours allowed to be moved? And does both or only one king need to reach the other side?

@Adam For one, please use proper grammar. And there kings stay where they are throughout the entire game, based on how the diagram looks. I’m already working on how to find even just one way to reach this position. I’ve already gotten some progress.

@Adam - This is called
Retrograde analysis
, and the standard constraint is that you are supposed to figure out how the position was arrived at via the normal rules of Chess - that is, alternating white and black moves, with white moving first, no unannounced checks, no failures to escape check, no illegal moves, and so on.$endgroup$

@RewanDemontay Why? That comment was unnecessary... telling someone to use "proper grammar" is quite an obnoxious statement. In general, grammar police-ing isn't necessary unless the grammar is so bad that the comment becomes unreadble. If it ever gets to that point, you can ask politely for that person to clarify rather than outright telling them that they have a bad grammar: Not only does that not fix any problems, but also creates conflict. We try to avoid that here. :)
