A bit of context might help. Is this an icebreaker? Energiser? Are you looking for learning outcomes? We have dozens of potential activities but a bit of context would help.
I would like to know a little more about what you are looking for. Games don't build teams - that's done by good management. If you need teambuilding, then start by addressing the way the team is managed. A game for the team won't change anything.
If you simply want a game, let us know and I can suggest lots. But, as posed, the question is asking for two different things.
Im looking for game ideas that would be festive to play during annual holiday meeting. the games should involve a group of a 100 . Thanks in advance :-)
You can find here hundreds of games and exercises in this public library of facilitation methods, among them a few dozens of teambuilding activities: https://www.sessionlab.com/library
I hope you find it useful
As others have been saying, suggestions do depend on a variety of factors from budget to learning outcomes.
I will assume for now that this is all about Christmas fun, correct me if i'm wrong! If budget is low and it's all about fun then a quiz is always a winner. If you have a little bit more to spend then something like Beat The Clock (supplied by companies such as Blue Hat and Team Challenge Company) is a great, fun activity to celebrate.
I must say I disagree somewhat with David's suggestion that games don't build teams. They have the ability to build team cohesion and understanding, and are great for giving people a 'safe' environment to grow as a team and develop the 5 behaviours of highly functioning teams. Effective facilitation and management is integral, but gameplay is where people can develop their skills and grow as a team.
I have loads of Xmas goodies, send me a note to my e-mail at [email protected] and I will send you copies. They are all my own so no worries about copyright.
Although this seems to be geared toward families there is definitely some inspiration in there in terms of team building activities: https://unicefkidpower.org/fun-family-activities-resources/
