MINNEAPOLIS (AP) - Changes are in store for electronic pulltab gambling in Minnesota, which never generated the revenue anticipated as a funding source for a new Minnesota Viking stadium.

The largest company distributing the iPad games to about 120 bars and other venues in Minnesota, Express Games, will cease operations at the end of the month. The charities notified of the change have been encouraged to sign on with Express Games' founder Jon Weaver and his new company, Pilot Games.

Gambling leaders say the changes are the result of declining interest in the electronic games and a lawsuit between Express Games and a competitor, Acres 4.0. Acres CEO John Acres says his company is shifting focus to casino activities.

Weaver says Pilot Games has developed "the next generation of electronics" and will develop new marketing tools.
