Casino revenue figures for 2015 were released on Wednesday and they tell a dismal story about gambling in Atlantic City. The win totals for the past year were 6.5 percent lower than 2014 and just half of the revenue generated ten years ago in 2006. The N.J. Division of Gaming Enforcement said that casinos in Atlantic City won just under $2.6 billion, after wining over $2.7 billion in 2014. Four casinos closed in 2014 and competition from neighboring states has negatively affected gambling revenue since it’s peak of $5.2 billion in 2006. On a positive note, monthly casino revenues were up by 0.6 percent for December over 2014.
