Jarrett Jack came back with a running jump shot to bring the Warriors within six. They forced a stop before Curry missed a runner that sent fans heading for the exits. Curry finished 5 for 18 from the floor, while Thompson was 1 for 13.
Both teams shot 45.6 percent.
Toney Douglas' free throws put the Kings ahead by eight with 32 seconds left, and then Sacramento got sloppy. Curry made a layup, then stole the inbounds pass from Patterson for another layup to trim the Kings' lead to 100-96 with 20 seconds remaining before Sacramento sealed the game on free throws.
"I think it's deeper than (matchups)," said Thomas, who shot 10 of 18. "The game before tonight we didn't really play too well. They killed us in everything, so I don't think it's just the matchups. We just came out and executed."
Most of the game followed the familiar Kings-Warriors script.
Offensive outbursts led to defensive droughts. Dazzling dunks morphed into poor finishes. And any time an offense flowed for a long stretch, eventually the rhythm shattered.
John Salmons started the silliness with a shot from beyond the arc while getting fouled by Barnes on the game's first play. The four-point play helped the Kings go ahead 12-2 before they hit their first rut.
The Warriors received contributions from all over during a 31-12 run that lasted midway through the second quarter. Lee and Bogut highlighted the spurt with a series of uncontested dunks off pick-and-rolls, often making an extra pass to the other inside to give Golden State a 33-24 lead.
There were 10 lead changes and five ties in the first half alone. The Kings led 47-44 at the break.
Sacramento surged ahead 64-52 in the third quarter after a 13-0 run sparked by Thomas, who scored 17 points in the third quarter, including going 5 of 6 from beyond the arc. The undersized point guard punctuated the period with a 3-pointer from the top of the arc in the face of Curry that put the Kings up 77-66.
If this really was the last time these teams meet as Northern California neighbors, the margin couldn't be closer. The series is tied 185-185.
NOTES: Boston Celtics great Bill Russell, who attended Oakland's McClymonds High School and the University of San Francisco, sat in a courtside seat next to Warriors executive board member Jerry West and team owner Joe Lacob in the first half. ... Curry made his 600th and 601st career 3-pointer.
