Start with a bingo card with a long list full of characteristics, facts, and qualities such as:
_________ has with brown shoes
_________ is wearing a red jumper or shirt
_________ is an only child
_________ drives a green car
_________ memorised this bible verse: _____________
_________ is wearing odd socks
You also need a whole lot of pens or pencils.
Photocopy the card so there's enough to give each person one.
The aim of the game is to complete your card - find someone else in the group that has that quality/characteristic/etc and write their name next to it. The first person to complete the card and shout "Bingo!" is the winner!
This game works really well as an ice breaker for all ages. Make sure the questions suit the age group, and make sure there are some easy ones and some hard ones!
