Question

I get stuck at some stage of the game. Pliz help.

Answer 1

sounds like you know the basics ...

when you get stuck, go through every blank square and see which numbers will go there. Write them small in pencil. You may find that some squares will only have one answer, and that may be the key ...

... or there may be 2 squares in the  one are with the same two possibilities ... no other squares there could have those numbers.

hope that helps. I get through some of the toughest using that strategy

Answer 2

trial and error, if there's absolutely no way you can get it with elimination...
