No, I'm not Tuumble's manager. (I am a member of the Chartered Management Institute though!)
If I had let Tuumble win, I would have left it at that and said nothing.
Workplace dilemma... Page 3
It's yours Tuumble. Like you said he should have declared it on the night. Take it home, wrap it up and make your kids happy at Christmas. The joy you give them, will wipe any guilt from your mind.
Just lie and say you already gave it to someone as a birthday present.
Well then ask the manager what he expects you to do.
Poo in the box reseal and then give it to him, late comisserate on working for an organisation that gives out nicely wrapped poos as prizes.
But more seriously don't mention it, let him be the asshole if he must.
Almost all comps will have rules that all decisions are final on the night.
Are you sure you#re not blowing this out of all proportions? Are you sure he mentioned it in away indicating he wanted the prize?
That said it is a bit of a sucky prize for a work do.
For another 100 squids they could have got an X360 elite with that game Burt Reynolds advetises.
I've been to company parties with similar 'fun' casinos. I either completely blow the pretend money on one crazy bet, give it away to some of the other party goers that seem to be enjoy themselves at the casino or find the money in my bag the next day. I know at these parties the management are happier if the employees win the prizes.
You've won it fair and square, but I wonder if you're feeling a little guilty because you didn't earn it in any traditional way? I know I probably would.
Hope your children enjoy it. 
It's your take it, tell him to jog on.
He was probably just sharing one of those self-deprecating "I'm such a dumbass guess what I did" stories with you and didn't realise the implications.
But if he did ask for it then:

BTW, the venue for our Christmas do where all this stuff happened was Down Hall where Jade Goody is getting married today
He shouldn't have told you about it at all, It's just made you feel bad necessarily.
If he wants to go to whoever gave out the prizes & explain his stupidity then they might buy him another one.
I doubt they'd ask you for it back, especially as you've already given it to an orphanage as a gift

Yeah, never mind all that gumbo tumbo, hope you kept the winnings and slept easy. The winnings were yours. Them's the rules.
I did keep it and I can see it from where I'm sitting right now
