The results for Saw IV were on par with the debut of Saw III, which pulled in $33.6 million (£16.3m) over the same weekend last year.
Since the original low-budget Saw became an out-of-nowhere fright sensation in 2004, Lionsgate has released a new chapter each October.
"I would expect to see Saw V next year, Saw VI the year after that and Saw VII the following year if they can keep it up," said Paul Dergarabedian, president of box-office tracker Media By Numbers.
"There's just something inherently gruesome and compelling about these movies. I don't know what that says about society in general, but it certainly works at the box office." he said.
Overall Hollywood revenues declined for the sixth straight weekend, taking $86.1m (£41.8m), although business was only down 2% compared with the same weekend last year.
