Two players face each other and clap out a fixed rhythm, alternating between clapping their own hands and their partner's hands.

Add a chant or counting rhyme that matches the beat of the claps.

Speed up the clapping pattern round by round while keeping the sequence accurate.

A player who claps out of turn, misses a beat, or breaks the pattern loses that round.

Restart at a slower tempo and build speed again, or move on to a harder clap sequence for the next round.
