Minnesota House members are considering ways to make electronic pulltab games a more reliable source of funds for the new Minnesota Vikings stadium. The House Commerce Committee met Tuesday to discuss the lagging pulltab sales by charitable organizations at bars and restaurants. So far the games have raised far less tax revenue than first projected. One suggestion was to set aside 15% of net revenues from the games to market and advertise them. Another called for scrapping a requirement that all electronic pulltab operators must also offer paper versions of the games, or lifting the total number of electronic betting devices allowed at a single location for those bars where the games have been successful. Lawmakers are also considering new sports memorabilia and stadium luxury seats taxes to backfill the stadium construction fund.
