The Battlestar Galactica, where two rollercoasters shoot off at the same time and loop around each other, will "only be opened when we have determined the cause and the solution,” a spokeswoman said on Friday.
"The ride may be closed for several days or longer to perform a complete analysis. We understand some guests may be disappointed; however, the safety of our employees and guests remains our top priority," the park said in a statement.
The glitch at the rollercoaster, the flagship attraction of the new Universal Studios park, was found during daily pre-opening testing on Thursday.
The world's fourth Universal Studios welcomed its first visitors on March 18 with a lavish ceremony aimed at attracting luck, and repeat business, to the Singapore theme park.
The park is part of the $4.4 billion Resorts World at Sentosa, owned by a unit of Malaysia's Genting Group, which also has a casino and six hotels, and plans to lure 60 percent of its visitors from Southeast Asia, China and India.
