For all members who regularly book courts at Sports Halls: Saw a notice on CCK Sports Hall that the public booking system will be changed from current Tuesday every week for the next 1 week to "EVERYDAY for the NEXT 2 WEEKS". This new system is similar to the Community Centre booking system. You may want to find out more from the staff at your regular/nearby sports hall.
