You are the assistant referee. The attacking team play in pink, the defenders in blue. The play freezes the moment the ball is passed. Look at the attacker the arrow points to. Are they nearer the goal than both the last defender and the ball? Then it's offside - tap Flag. Otherwise tap Play On. Watch for the tricks: level with the last defender is onside, you can't be offside in your own half or behind the ball, and there's never offside from a throw-in, corner or goal kick. Every player wears a number so the reveal can talk you through the call, and an attacker in an offside position only counts if the ball is actually played to them.
🚩 12 offside calls - score out of 12. How sharp is your eye, linesman?
The line sits on the last defender. Beyond it when the ball is played is offside - level, behind the ball, or in your own half is onside.

Flag it, or play on?
Judge the attacker the arrow points to at the frozen moment. Offside = nearer the goal than both the last defender and the ball. Level, behind the ball, own half, or a throw-in/corner/goal kick all mean play on. The reveal draws the offside line and names the players by number. An attacker who is offside but not the one the ball is played to doesn't count - play on.
