Tug of war (vadam vali) is a sport that is an inevitable part of Onam festivities in Kerala, India.

Also known as rope pulling, this sport involves two teams of eight set against each other in a test of strength.

The teams start with the rope's centre directly above a line marked on the ground. Roaring spectators cheer the teams standing on the side of their favourite team.

Once the contest (the "pulling") has commenced, each team try to pull the other team to their side. The team that successfully pulls the opponent to their side crossing the centre line will be declared as winners.

The sport is popular among both men and women. If the opponents commit a foul (such as a team member sitting or falling down), they lose.
