Some games don't end if you can't move, you have to pass! e.g. Lines of Action/backgammon/Ludo

The rules mention "How to finish the game" and it is an omission to not mention the possibility of stalemate.

It is reasonable to expect the game is not finished when the conditions are not met?

Since check is forbidden, why assume stalemate is the same when there is a section on how the game end that could include stalemate and doesn't mention stalemate?

The rules need amending, had the rule been clear I would have played another move!
