Having created four millionaires in as many years, Singapore Changi Airport kicks off its fifth annual Be a Changi Millionaire sweepstakes this month. Through Oct. 31, millionaire wannabes need only shop and dine at Changi Airport to qualify for a chance to land the windfall.

The 2013 promotion saw an overwhelming participation rate of 2.2 million lucky draw entries, more than 2.5 times its inaugural run in 2010. During this year’s six-month shopping promotion, one finalist will be drawn each month to qualify for the grand draw in early 2015 when all six finalists will gather at the airport for the grand finale. Five of the finalists will go home with $5,000 each while the grand prize winner will collect the $1 million grand prize.

Throughout the promotion, airport shoppers may be eligible for instant prized including and Apple iPad Air, a Mont Blanc pen, a GoPro Hero3+ camera, shopping vouchers and travel accessories.

To qualify, shoppers must make a minimum purchase of $30 at participating venues. The number of winning chances increases with the amount spent. Additional chances will be allocated for Changi Rewards card members and iShopChangi.com purchases.
