Ecuador or Serbia, who will kick off?

Serbia. Ecuador kicked off with Serbia, and Serbia learned that the kick-off of a game was decided by both sides by flipping a coin or drawing lots. When kicking off, the cue ball should be placed at any point in the kick-off area (D-shaped area) to hit the ball. The principle is to prevent the cue ball from falling into the bag and not leave the opponent with a chance to score continuously.
