What I've found is you need to strip the games down and make them as simple as possible. You can ignore all the little details until after they understand the main idea.

Duck Duck Goose

(demonstrating with the group as you verbally explain.)

Maka a circle.
Sit down.
I go around.
I touch Kenny.
Kenny stands up.
I run.
Kenny runs.
I sit down.

Kenny goes around.
Kenny touches ...

I'd leave out the whole 'Duck.' 'Duck.' 'Duck.' 'Goose!'

Once they understand (day 2) you can have them use real language, which might be better.
'Not you.' 'Not you.' 'Not you.' 'Not you.' 'You!'

Then later (day 3) explain that the person touched can try to pass the person to sit down first.

That's all the rules, right?
