Minnesota: Shakopee tribe challenging legality of electronic pulltabs Rochelle Olson, Star Tribune · February 14, 2020 at 3:27 pm Electronic pulltabs, the source of public funding for U.S. Bank Stadium, are facing a legal challenge from the Shakopee Mdewakanton Sioux Community that could staunch the flow of state revenue from the games to the stadium. In a legal petition to the Minnesota Gambling Control Board, the Mdewakanton Sioux contend that an “open-all” feature for e-pulltabs mimics their video slot machines and threatens their business.Under the compacts negotiated with the state three decades ago, Minnesota tribes have exclusive rights to operate slot machines on their reservations. The “open-all” feature on the video games all windows to be instantly revealed with a single touch. Paper pulltabs, on the other hand, require that each line be opened manually. The gambling board, which oversees charitable gambling in the state, disputed the premise of the tribe’s claim.
