Birthday Party Games For Senior Citizens

I am planning my Mom`s surprise 80th. Birthday. Here are two games I am doing while the guests wait for her arrival.
As each guest arrives I will give them a list of questions about my Mom and one clue. The object is to thru mingling find as many answeres as possible. The winner gets a prize. You might want to, before the party, ask each senior to write down one unusal thing about themselves. Form a list and hand out clues. It`s a great mixer. I am also making a crossword puzzel using words that retate to Mom. Hope this helps.
