A small crowd of curious passers-by gathered in front of a giant spinning wheel at the People's Park Complex hawker centre, near a poster with instructions on how to play the game and win prizes: Buy a healthy meal to get a game voucher, download an app, then spin the wheel.

A staff member manning the wheel told an elderly couple: "No, I am not giving out a car or a condominium, but you got these prizes." He pointed to the wheel, with segments that read "Milo 3-in-1", "wholegrains cereal beverage" and so on.
