How I search a specific Played/Rated Item if it isn't in a List?

I have difficulties to find a specific Videogame I played, but I never put it in a List I wanted [I forgot back then].
I tried really hard to find it...but I failed....

Is there a trick to find this item which I want to put in a List.

I must note ALL other games I played + rated, are already in a list.

Thank you for your help!!!
