Wade dropped just one set to reach the quarter-finals of the 2012 World Championship, but was then involved in two of the best games ever witnessed at the event. He played John Part in the last 8 and raced into a 3–1 lead before the Canadian won three sets in a row. Wade took the game into a deciding set and the players broke each other's throws twice to require a sudden-death leg, which he managed to win by taking out 85 with Part on 40. He played defending champion Adrian Lewis in the semi-finals and looked to be heading for his first PDC World final as he led 5–1. Lewis pulled a set back, before Wade had a dart at double 18 to win the match. He missed and it proved to be a pivotal moment as Lewis took the set and reeled off 10 straight legs to complete a sensational comeback 5–6. Despite the loss, Wade moved up to third in the PDC Order of Merit overtaking Gary Anderson.
