But screaming at people to shush because they’re not doing what you want is going to result in people walking away. Teaching your child anything else wouldn’t be doing them any favours. If my child told me their friend screams at them to shush if they don’t play the game exactly how the friend wants I’d specifically tell them to walk away from that friend.
I definitely wouldn’t be apologising and asking her to explain it again to ‘silly mummy.’ I’d tell her she was being rude and using unkind words, and until she could be polite I would choose to do something else.

Ok, but that's not just walking away, is it?
Walking away is a form of shunning. You shouldn't tell your child to do this to another child without teaching him to assert himself verbally first. It if doesn't work, then sure, tell the shouty kid you'll play again when he's ready to be calm. But simply walking away is passive aggressive, and not positive behaviour. It's quieter than shouting, but that's all it has going for it.
As a parent, failing to engage verbally with the child who is shouting (not screaming) "Shush" is not modeling the verbal approach to dispute solving or teaching assertiveness. It is punishing a flawed verbal approach ("Shush") without trying to teach the alternative, which is how to tell 'silly mummy' she's doing it all wrong and what is required of her instead in a reasonable voice. You can teach a child to be assertive instead of being overwhelmed by frustration. Assertiveness is a skill girls need.
And a parent who is playing with a young child (four is pretty young) needs to watch the child's cues for signs that things are getting overheated.
