I making a memory card game but dont have to much examples and documentaion's

Need blueprint’s or some video tutorials rly need do this game on UE4 because i like it it cool

What is your question again? You want someone to google tutorials for you?

Something as specific as a niche game (that you have on your mind) genre tutorial may simply not exist. Break it down into smallest components and work on those.

Or visit the marketplace and see if there’s a template that you download / buy.
