Nevada’s cash game poker market is on a five-month-long consecutive wins.

The state’s poker rooms brought in $8.7 million from the games in September, according to figures released this week by gaming regulators. The amount was the best September for the rooms from as far back as the $8.9 million in revenue generated four years ago, according to data compiled by the University of Nevada Las Vegas’ Center for Gaming Research.

Nevada had 62 poker rooms with a total of 598 tables in September 2017. There were 80 rooms with a total of 755 tables in September 2013. That was the month that the WSOP started off its online poker site in the Silver State. These days it is the only iPoker operator in the state.

The $8.7 million was a 3.5 percent more compared to the $8.4 million raked in September 2016. Nevada poker rooms have posted year-over-year revenue increments since May.

The previous time the rooms had a winning streak that long was between June and November in 2013.

The best September ever for Nevada’s poker industry was back in 2006, when the rooms brought in $12.6 million. That was at the height of the poker boom in the Silver State.

Over the 12 months prior to Oct. 1, 2017, Nevada poker rooms took in $118.2 million, a third of a percentage point more compared to the same period the previous year.

In July, rake of $12.4 million was the best for the rooms for that month in six years.

The WSOP, which ran from May 30 to mid-July, set a joining record in 2017 with 120,995 entries. The number of entries was also incrementing 12.2 percent year-over-year. There was a record 74 tournaments on the schedule, paying out as much as $231 million in prize money.

Nevada poker could soon get a boost thanks to a three-state liquidity sharing agreement with New Jersey and Delaware. Furthermore, Pennsylvania’s online poker bill passed into a law this week, and the Keystone State could provide even more players in the combined player pool.
