The Minneapolis-St. Paul International Airport became one of the first airports in the nation to launch electronic gambling in January, projecting that the iPad games in bars and restaurants would rake in $3 million in 2013 to help fund the Minnesota Vikings stadium.
Six months later, however, passengers have spent $33,586.
The disappointing returns are the latest indication of problems with the state's original plan for funding the state's $348 million share of the stadium.
On Monday, a Metropolitan Airports Commission (MAC) committee voted to let the gambling experiment continue. The commission had approved a six-month run in January.
So far, only two of the six airport bars and restaurants now offering electronic pulltabs are bringing in significant cash.
The e-game rollout was delayed because software and wireless connections had to be revamped for use in an airport that has hundreds of employees with access to them. That took several months.
In the weeks ahead, staff at the airport bars and restaurants will be trained on how to encourage customers to give the games a try, so that year-end numbers will be far stronger, said Jana Vaughn, executive director of the MSP Airport Foundation.
"It's a daunting task," said Vaughn. "This is hundreds of people [staff] getting one-on-one training. But we think this will ultimately be successful."
