Game where spots are awarded as a forfeit - winner is the one with fewest spots
Sticky spots, blank name tags
The winner is the person with the least amount of measles.
At the start of the party give everyone a sticker with a made up name. For example, Joe Bloggs or Fred Fart. This is good if it's a theme party. You can use names like Captain Crook, Pearly Pink etc.
Everyone has to use their made up names throughout the party and not their own names. If someone hears a person saying their own name they have to shout "measle!". The person who said the name not on the sticker gets a red spotty sticker.
Surprisingly hard especially at a party where everyone knows everybody really well!
