The 17-year-old girl, was found hanging in her house at around 7:30pm in Nagpur's Beltarodi area on December 4, the official said.
He said the phrase "cut here to exit" was written with ink on her wrist.
"We are trying to find out which games she used to play online and whether these were dangerous ones. We have sent her mobile phone to the forensic lab for analysis," Talware said.
He, however, added that preliminary investigations have also suggested the teenager was depressed.
He said the girl had secured good marks in her Class 12 exams but had dropped a year to get into a college of her choice.
An accidental death case has been registered and further probe into the incident was underway, the official said.
