Here is a dice game that can be played at any party, we made it for Christmas. You just need one scratch off ticket for each person. I went the extra mile and wrapped each one in a gift bag so no one knew what was inside.
I put either a $1, $2 or $20 scratch off in each package (we did only one $20 scratch off). Then you grab a pair of dice and follow the directions here Party Dice Game.
Hopefully you will enjoy some laughs and someone will win a very big prize!
