This is much less complicated than it sounds. It works for numbers from eight upwards and is suitable for kids aged eight onwards.

1.Kids stand in a circle, adult stands in the middle.

2.Adult makes custard pie gesture towards one child, shouting 'Splat!'.

3.That child ducks.

4.The children on either side of this child in the circle shout 'Splat!' at each other, and make a splat gesture. No physical contact!

5.The slowest child of the two is out and sits down, but stays in the circle. If it's a tie, they both stay in.

6.Eventually, you'll be down to two kids. They have to have a 'Splat!-off'. They stand back to back, and take a step forward every time an adults says a word. When the keyword (eg, 'Splat'!) is shouted, they have to turn and splat each other. The winner wins, the loser is second.

Optional rules: when they get the hang of it, kids can also be out for not ducking quickly enough, or for shouting 'Splat! at the wrong time.
