Seoul, March 3 (Reuters): A South Korean software firm has found a way to help people appear to be hard at work while they are actually playing computer games at their desks.

Software maker CCR has developed a system by which workers can play card games with icons planted at the bottom of the screen. The icons look like short-cut keys on a tool bar. While a worker is busy playing by clicking what appear to be normal icons, all a passing boss can see on the screen is pressing work.

?I usually enjoy playing the game with my co-workers during lunch time but I can sneak in some playing during my working hours as well,? said an office worker.

CCR said it has applied for a patent and wants to develop more games that will allow workers to play on the sly.
