Thousands of Keno punters were left in the lurch on Saturday night when the gaming operation experienced a system-wide memory glitch.
Keno screens in all 1004 clubs, pubs and hotels that host the game in NSW went blank between 1:13am and 1:54am on Sunday.
A spokesperson said the central Keno memory board experienced a failure in its cluster set. The memory board was replaced immediately, she said.
"It definitely wasn't software".
Although it received no official customer complaints, Club Keno received phone calls from six clubs during the outage.
The spokesperson said the gaming operation would not offer refunds to players whose games were interrupted by the outage. However, those punters' playing tickets would still be considered valid once the system returned to operation, they said.
The standard Keno closing time of 2:00am was not altered as a result of the outage, they said.
The memory glitch did not affect the 830 establishments that run Keno in Queensland, the spokesperson said.
Clubs purchase playing screens outright from Club Keno. The clubs then pay ongoing fees for quarterly technical maintenance, the spokesperson said.
