An instant horse racing parlor in eastern Idaho says it has been forced to shutter its doors and lay off 70 employees. The Post Register reports that Double Down Betting, Sports Bar and Grill announced its decision Wednesday. Co-owners of the establishment say the closure is a result of a recent Idaho Supreme Court ruling that made lucrative instant horse racing machines illegal in Idaho.Instant horse racing allows bettors to place wages on prior horse races with no identifiable information. The machines have spinning wheels, sounds and animations that mimic slot machines. Gov. C.L. “Butch” Otter vetoed legislation banning the machines earlier this year. However, the state’s highest court later ruled that Otter failed to issue the veto on time. Double Down operated 80 instant horse racing terminals. After years of declining revenue, the slot-like machines were seen as a much-needed shot in the arm to revive the sluggish industry. That’s because portions of the profits went to the track owners and breeding groups, with the amount paid to the highest finishers at live races/Associated Press.
