Seeing cards at the end of a game?

Hi, Newbie here! Greetings from across the pond.

Apologies if this has been covered before but I don't seem to be able to find anything!

I thought at the end of a game I would see all of the players hands that had stayed in till the end, but this doesn't seem to be the case! It seems to vary!

Cheers

Will

According to the rules it goes like this:

The last guy that bet HAS to show. The callers don't have to. So let's say I bet the flop, and 3 guys call, and then turn and river get checked down. Then I have to show my hand. If one of the callers has a better hand, he has to show it to claim the pot, or he can simply announce he doesn't have a better hand and muck it without showing. In this example, you would only get to see all 4 hands if the first caller has better than me, so he shows. Then the guy behind him has even better and shows too. And the last guy shows with the winning hand.

Cheers, much appreciated.

However, Many times if you check the hand history you can see what people mucked
