Just learnt of a really nice little ice breaker game called "Memory Lane", suitable for corporate meetings and any number of people.
Ask the group to think about a major event that happened in the year they were born. Then ask each person in turn to describe the event to everyone else in the group. Everyone else has to guess the year.
A variation could be to ask for 2 or 3 events for the year to make it a little easier. For more great ideas to kick-start meetings and events you can still get my ice breaker games collection at a reduced price for a limited time only. Why scour the internet for ideas when you can get a full set of our very best ice breakers that we have used for 20 years!
