Games from trilogy Crime Santa Clause display both titles "Crime Santa Clause" and "Crime Santa Claus". For instance, these are loading screens from demo and final version of the same game:





Does anybody know what's the correct title? If both titles are correct, are they from different idioms?

I suppose you could get answer only on zx.pk.ru

But I know this game quite well and would say that you can treat both forms as equal.

By the way, it's great, although unfortunately available only in Russian.

If you look closer, you might notice even a third (?) title there, which is 'Crime of the Santa Claus' I don't know for a fact but I really doubt any of this is intentional and/or has some additional meaning.

IIRC, one of the authors is Slider, who is also on WoS.
