Racetrack video lottery saw the biggest decline, from $58.5 million to $53.9 million.
Lottery officials said increased competition from casinos in neighboring states is to blame for the declines.
Also at Thursday's meeting, commission members fined Kelly McGill, owner of Kelly's Hot Spot II in Dunbar, $3,000 after technicians tampered with video lottery machines in the bar.
The commission in April fined Kenneth Howell and Lawson Mangum $1,000 each and placed them on six months' probation. The men, technicians for Clarksburg-based Shafer Amusements, admitted they "wired over" switches inside 10 video lottery machines.
Tim LaFon, McGill's lawyer, asked that the commission not fine McGill for the tampering, because he said there was "not one shred of evidence" showing she was complicit in the acts.
"I'm not sure she could rewire one if she wanted to. If a machine breaks down, she calls the technicians," he said.
Lottery director John Musgrave said state rules require license holders take responsibility for machines covered by their license.
McGill refused to speak to the Daily Mail about the fine.
Commissioners also fined the American Legion Post 19 in Logan $5,000 for various offenses, including allowing patrons to play video lottery machines on credit and holding checks.
No members of the post were present for the commission's meeting.
