The move comes two days after a girl in Jodhpur attempted suicide after playing the game.
Singh in an order asked police authorities, education officers and NGOs to conduct one-hour awareness session in schools and colleges to sensitise youths about the game.
The DGP also asked them to take the help of counsellors and psychologists.
Singh appealed to parents to keep an eye out for changes in behaviour of their children to prevent them from falling prey to the online game.
