His reading of the game and his ability to improvise on the fly were unrivaled, and he could consistently anticipate where the puck was going to be and execute the right move at the right time. His coach at the Edmonton Oilers, Glen Sather, said, "He was so much more intelligent. While they were using all this energy trying to rattle his teeth, he was just skating away, circling, analyzing things."

He was also considered one of the most creative players in hockey.

Wayne Gretzky [SEP] Style of play
He passed and shot with prodigious skill. Hall of Fame defenceman Bobby Orr said of Gretzky, "He passes better than anybody I've ever seen." In his first two seasons in the NHL, his deft passing skills helped earn him a reputation as an ace playmaker, and so opposing defencemen focused their efforts on foiling his attempts to pass the puck to other scorers. In response, Gretzky started shooting on goal himself—and with exceptional effectiveness. He had a fast and accurate shot. "Wayne Gretzky was one of the most accurate scorers in NHL history", said one biography. Statistics support the contention: whereas Phil Esposito, who had set the previous goal-scoring record, needed 550 shots to score 76 goals, Gretzky netted his 76th after only 287 shots—about half as many.
