This is a fab book (though unbelievably dated!)
8-year-olds - the BEST age for games. For ds's party we are going to have to go to a community centre, so we can't do the best of all - MURDER. You know the drill - using 10 cards, one of which is an Ace and one a Queen, choose a detective, who says who she is (Ace), choose a murderer who keeps it quiet (Queen). Turn lights out and scatter - parents stay by the light switch with a glass of wine. Murderer chooses a victim and whispers in her ear 'you've been murdered'. Victim has an enjoyable time screaming her head off while murderer slinks away. Detective and parents hear the scream, count to ten and turn the lights on. Everyone comes into one room. The 'detective' questions the guests as to where they were, what they heard, who was in the room with them etc. Everyone HAS to tell the truth except the murderer - you need to ensure they all understand the game doesn't work unless they do. The detective gets one guess - if right, she wins, if wrong the murderer wins. Repeat.
We are using the following games among others:
Pairs - pairs of characters on postcards torn in half and pinned to the backs of people's shirts as they arrive - they ask yes/no questions about their own character and then have to find their pair.
Pictionary - but old-school. Question master has a list of things to draw. TEams in separate rooms race to and from the question master, drawing with pencil and paper until everyone has had a go/the list is finished. Teams of 5 should be fine. Very extreme.
Hunt the ring - sit in the circle, string all round, small ring on string. One person in centre. Ring passed from person to person, she tries to spot it, changes over if she guesses/after 3 goes.
Emergency games - Kim's game; just keep a tray of ? 20 things with a tea towel over it - they look, you cover, take one, uncover, they guess which has gone.
You are liberated from pass the parcel at this age. Rejoice!
