— The Maryland Lottery is up to its old tricks again with a faulty scratch-off game that officials say may be breaking state gambling laws.

The state’s attorney general will investigate, said his spokeswoman, Abbe Smith.

The embarrassing gaffe followed another this year in which game prizes went unclaimed, The Washington Post reported. Officials said a similar problem had happened in the past as well.

For the latest game, customers were offered a chance to win a $10,000 prize by guessing the winning numbers in a Keno game or by choosing their own. The $10,000 prize is equivalent to the minimum payout the state keeps for Keno.

But after no one won the Keno, Maryland Lottery officials announced that the game was being renamed “The Who Game” and would offer a $1 million prize. Players who played the game this year picked their own winners and a winner was drawn on Dec. 7. But one prize didn’t match the numbers, so the $1 million prize didn’t go to anyone and the $10,000 prize did not get paid out. Officials said the catch was that the drawing was to take place on Nov. 30, the same day they held their keno drawings.

The two previous keno winners and winners of a jackpot in another game both won the prizes on the same day.

The story prompted Maryland Democratic Gov. Larry Hogan to take to Twitter to insist that the lottery had notified its vendors of the mistakes and that none of the winning prizes were lost.

“The winning numbers were not compromised,” Hogan tweeted. “We always keep winners notified.”
