Each group played a round-robin format. Two points were awarded for a win and one point for a draw, with goal average used to separate teams equal on points. The top two teams in each group advanced to the knockout stage. In the knockout games, if the teams were tied after 90 minutes, 30 minutes of extra time were played. For any match other than the final, if the teams were still tied after extra time, lots would be drawn to determine the winner. The final would have been replayed if tied after extra time. In the event, no replays or drawing of lots was necessary. The draw for the final tournament, taking place on 6 January 1966 at the Royal Garden Hotel in London was the first ever to be televised, with England, West Germany, Brazil and Italy as seeds. Eight venues were used for this World Cup. The newest and biggest venue used was Wembley Stadium in west London, which was 43 years old in 1966. As was often the case in the World Cup, group matches were played in two venues in close proximity to each other. Group 1 matches (which included the hosts) were all played in London: five at Wembley, which was England's national stadium and was considered to be the most important football venue in the world; and one at White City Stadium in west London, which was used as a temporary replacement for nearby Wembley. The group stage match between Uruguay and France played at White City Stadium (originally built for the 1908 Summer Olympics) was scheduled for a Friday, the same day as regularly scheduled greyhound racing at Wembley. Because Wembley's owner refused to cancel this, the game had to be moved to the alternative venue in London. Group 2's matches were played at Hillsborough Stadium in Sheffield and Villa Park in Birmingham; Group 3's matches were played at Old Trafford in Manchester and Goodison Park in Liverpool; and Group 4's matches were played at Ayresome Park in Middlesbrough and Roker Park in Sunderland. The most used venue was Wembley, which was used for nine matches, including all six featuring England, the final and the third-place match. Goodison Park was used for five matches, Roker Park and Hillsborough both hosted four, while Old Trafford, Villa Park and Ayresome Park each hosted three matches and did not host any knockout round matches. The opening match took place on Monday 11 July. With the exception of the first tournament, which commenced on 13 July 1930, every other tournament (up to and including 2018) has commenced in May or June.
