VAR at the World Cup: Complete Rules Guide

Since 2018, VAR has fundamentally changed how matches are officiated and how fans experience key decisions.

How VAR Works

VAR can only intervene for goals, penalties, direct red cards, and cases of mistaken identity — nothing else.

The handball rule generates the most controversy. Judging whether contact is unnatural involves significant subjective judgment.

Semi-automated technology produces precision to centimeters, creating offside calls invisible to the human eye.

VAR reviews can reverse goals in real-time, creating significant swings in live betting markets during the review period.

Teams with penalty-winning forwards should be assessed through a VAR lens as technology has increased penalty frequency.
