A double-double from Josh Giddey has lifted Chicago to a fifth straight win, with the Bulls charging home to prevail 109-102 against the Philadelphia 76ers.
Jalen Smith sparked a game-ending run with a thunderous dunk on Joel Embiid in Chicago on Friday night (local time).
The Bulls scored the final 10 points of the game, starting with Smith's driving dunk.
Giddey was restricted to 12 points, but still delivered six rebounds, 11 assists and a steal in the topsy-turvy clash.
Tre Jones and Zach Collins each had 15 points, and Coby White scored 13, helping the Bulls match their best streak since a 5-0 start. They also evened their record at 15-15.
Embiid led Philadelphia with 31 points. Tyrese Maxey scored 27 and had five three-pointers. Paul George shook off a slow start to finish with 15 points and a season-high 12 rebounds, but the 76ers lost for the fourth time in as many games this season with their three stars in the line-up.
The Sixers led 102-99 after Embiid backed in with 2:45 remaining, but that was all the scoring for them.
Smith then drove the baseline and dunked on a rotating Embiid with about 2:30 remaining, bringing the fans to their feet.
Meanwhile, Atlanta were outclassed 126-111 by the visiting Miami Heat.
Australian star Dyson Daniels had six rebounds, three assists, eight points and two steals as his Hawks crashed to their fifth straight loss.
Atlanta's Trae Young scored 30 points and Jalen Johnson had 24 points, nine rebounds and 10 assists for his 12th consecutive double-double, the longest such streak in the league this season.
Norman Powell scored 25 points and Pelle Larsson added a career-high 21 points to help Miami end their three-game losing streak.
The Hawks got as close as one point in the third quarter when Young nailed a three-pointer to cut the lead to 79-78, only to have Miami outscore them 11-6 to end the quarter and take a 90-84 lead into the fourth.
The Heat built the buffer to 15 points at 102-87, before Atlanta used a 9-2 run to cut the margin to eight.
But Miami scored the next nine points to take a 17-point lead and were never threatened.

Jaylen Brown scored a game-high 30 points for the Celtics, while Australian Johnny Furphy came off the bench to contribute nine points and two rebounds for the Pacers.
The haul means Brown has scored at least 30 points in eight straight games, one short of Larry Bird's franchise record for consecutive matches with at least 30 points (nine in 1984-85).
Former NBL Next Star LaMelo Ball had 22 points and seven rebounds to help the Charlotte Hornets beat the Orlando Magic 120-105.
