ROSEVILLE, Minn. (AP) — Minnesota regulators on Monday approved guidelines for new electronic gambling devices that are a major revenue source to offset debt on a new Vikings football stadium.

The Gambling Control Board voted unanimously for the standards, resisting calls from some corners of the charitable gambling industry to slow the rollout until more is known about how the hand-held devices will work. The action provides the guardrails for makers of the devices, which could show up in bars and restaurants as soon as fall.
