Glass jar tombola - you have to get everyone to start collecting glass jar with their lids (not ones that have had curry sauce or anything smelly though). Then you fill them with all sorts of things: felt tip pens, crayons, coloured cotton wool balls, dried pasta, tea bags, pegs, boiled sweets, etc etc. If you get any small glass jars (maybe those minature jam pots) you can put a 50p, �1 coin or fill it with pennies. Then charge 50p a go, Everyone is a winner. Always went down a storm when I did it.
Lottery Bonus Ball. Have a large sheet of paper with numbers 1 - 49 on it (someone I knew always drew 49 clouds shapes). �1 a go, write the persons name and phone number under their chosen number. The person with that nights lottery bonus ball number wins �25
Bucket of money. People buy a raffle ticket for �1, throwing the pound in a big bucket. At the end the winning raffle ticket gets half the money in the bucket. This is especially good if you can get �200 in the bucket, then the winner gets �100.
Chocolate tombola - like a normal tombola but all the prizes are chocolate related.
