I was on the way to the gate C17 on Sunday to catch my flight when I saw this game been hosted at the transit hall.

I checked my watch - 8.35 pm. My flight was 9.20 pm, so I thought a game wouldn't take too much time....

Little did I know that the game has 3 stage and I got into the final round with a Korean and an Indian contestant. I beat them and won a pen ;-)

I checked my watch again - 8.57 pm. I started running to my gate...
