EXCLUSIVE: Weeks-long computerized draw error prevented many DC Lottery tickets from winning a prize

Washington, D.C. Lottery

Certain combinations had no chance of winning for three weeks

By Kate Northrop

Following independent observations by Lottery Post members of an unlikely statistical anomaly in Washington, D.C. draw outcomes, the DC Lottery identified a software problem that meant certain combinations had no shot at winning prizes in three games.

The DC Lottery has implemented a fix for a coding error that prevented some tickets from winning in three of its local draw games for three weeks.

After Lottery Post members independently identified a statistically improbable occurrence in local Washington, D.C. draw results, Lottery Post staff reached out to the DC Lottery to inquire whether a problem with the drawing mechanisms existed.

"As of right now DC 5 has played all single digits 36 times in a row," Lottery Post member Newkids06 said on April 18. "Not 1 duplicate digit has been played in the 36 draws. Duplicate digits make up roughly 70% of the numbers. Mathematically this is impossible and seems to be what happened to Pick 3 and Pick 4 in Tennessee in 2007."

By the time the 40th consecutive drawing occurred without any repeating digits in DC 5, Lottery Post member JADELottery recognized enormous odds of the game continuing to draw combinations with non-repeating numbers. As he predicted, the 41st DC 5 drawing occurred with results (8-6-1-9-2) that only contained "singles," or what lottery players commonly refer to as non-repeating digits in a sequence.

According to JADELottery, the odds of the DC 5 drawing producing a singles combination without any repeat digits for 41 consecutive drawings is 1 in 242,413. It's not impossible, but improbable. By the time the game reaches its 50th consecutive drawing without a repeat digit, those odds become 1 in 3.685 million.

[Editor's note: As pointed out by Lottery Post member Brock Lee, the odds of observing 41 consecutive drawings, each with all distinct numbers, is actually much higher: 1 in 1.98 sextillion.]

On Tuesday, Lottery Post reached out to the DC Lottery to alert Lottery officials about the possibility of an askew drawing mechanism. Washington, D.C.'s local lottery games, including DC 5, are conducted via random number generator (RNG).

The following morning, the DC Lottery contacted Lottery Post with confirmation that they identified a coding error with three of their draw games after Lottery Post brought it to their attention.

"A configuration issue caused by a third-party vendor, Smartplay International, Inc., has impacted DC Lottery's draw machines for its DC 3, DC 4, and DC 5 mid-day and evening drawings," DC Lottery Chief of Communications Melissa Davis said in a statement to Lottery Post. "Prior to implementation, the draw systems were third-party certified by Gaming Laboratories International. A coding error prevented the machines from allowing for repeat numbers, such as 111, 222, 311, 229, etc. An investigation determined the issue began on March 31, 2026, during a routine draw machine recertification conducted by the vendor."

The issue essentially means that players who purchased tickets with repeating digits for the past three weeks had no shot at winning a prize in any of the three Pick-style draw games. Luckily, the Lottery has put a temporary solution in place so that future drawings are not impacted.

"As soon as DC Lottery discovered the issue, we immediately contacted Smartplay, who initiated a configuration fix, testing, and quality assurance," Davis continued. "Out of an abundance of caution, DC Lottery is reverting to a backup system to conduct DC 3, DC 4, and DC 5 drawings on April 22, 2026."

The DC Lottery is focusing its efforts on remediating and communicating the issue to players today, Davis explained over the phone. Tomorrow, they anticipate publishing a solution to make it right for players who may have lost out on potential wins.

"We are confident that we have identified the issue and are reviewing the entire process to prevent it from reoccurring," Davis explained. "We deeply regret the error and remain committed to upholding the highest standards of integrity and public trust, and will make this right for our players. Players who purchased tickets for the DC 3, DC 4, or DC 5 mid-day or evening drawings for March 31, 2026 — April 21, 2026, should hold on to their tickets and await further information from DC Lottery."

The same coding error took place with the New Mexico Lottery in 2019, in which combinations with repeat digits were impossible to be drawn in Pick 4. It went on for two weeks before the New Mexico Lottery identified the mistake made by their gaming vendor.

In 2021, another software glitch prevented the New Jersey Lottery's Fast Play Progressive jackpot game from selecting a jackpot winner for two months, meaning players were funding the jackpot with their ticket purchases without having any shot at winning it.

In 2018, a coding error made it so that 100,000 tickets had no chance of winning any prizes ranging from $100 to $1 million in the state's New Year's raffle drawing.

Other instances of computerized drawing mishaps have been well documented by Lottery Post over the years, with some the most notable examples below:

It is So Sad how we trust computers. Imagine what will happen when self driving cars Malfunction from bad programs who will be responsible. I definitely prefer real ball machines at least they can see a ball is missing not a Ghost 🐋🐋🐋🐋🐋

that math is not correct. the probability of singles occurring in any one pick 5 drawing is 0.3024. the probability of it happening n times in a row is 0.3024^n. that means the probability of pick 5 singles happening 41 times in a row is 0.3024^41 = 5.5065 x 10^-22. this is from wolframalpha, not chad g petey. https://www.wolframalpha.com/input?i=0.3024%5E41

SmartPlay should be banned from conducting business in the lottery.

Because they failed to do the most important job of fair play, I think it's time to just flat out stop playing the lottery.

to the dc lottery's credit, they addressed the issue way faster than i expected. some of those other states let their bad code run a long time before fixing it.

If I'm wrong, I can accept that, however, are we referring to the same thing?

I'm referring to the rate of reoccurrence and appears you're referring to the probability of existence.

I think it goes without saying that this is a failure for the industry, and specifically for SmartPlay.

The reason is that this specific error has happened so many times before, so not only the fact that their systems are allowing these kind of simple mistakes over the course of many years, but the fact that they do not have any monitoring software running that continually examines drawing results for easily-detectable patterns that should be investigated.

Why does SmartPlay not have AI software running every single day that looks for bad patterns in drawings??

In today's environment with easy access to powerful AI engines there is no excuse.

But again at the heart of the matter is that like we've been saying for so many years, lotteries should not be conducting daily drawings with computers. The FACT is that if the lottery (and all the other lotteries that previously made this same mistake) had used traditional ball drawings, this error would never have happened.

There are perhaps many thousands of tickets that were sold with no possibility of winning (and probably thrown away at this point), and many of those tickets would have won prizes if real ball drawings were in place.

All those people playing pairs, triples, quads, and even quints — all with no chance of winning.

Dreadful!

Why do I expect John Cheeks to show up soon and claim he was cheated out of a lot of $.🤣

Newkids06

Glad they fixed it because you can't really win much money playing box unless it's a double, triples, quads or Quints. Feel bad for everybody who threw away majority of the losing tickets. Hopefully DC now starts playing some favorable more popular combinations since they took everybody money for three weeks and won't be liable for all the losing tickets thrown away. Hopefully every state lottery can go to a live drawing. Similar to NC, VA, NY etc

Just wondering... What was their first/immediate reaction when you told them there could be a problem? Were they receptive to it, or did they give you the, "All draws are completely random independent events", line we hear so often before conceding there could be a problem? 

   This is just one more example why all lotteries should go back to mechanical ball drawings. The RNG's may be faster and cheaper for them to use, but players doubting the game's integrity is not good for their business.

Glad you brought it to their attention. Thank you!!

I agree with you 100%. Or atleast stop playing. And tell them to go back to ball draw games/ mechanically draws. And I thought lotterys had an outside source who audited these games? If they do. What happened there?

I have a bit of sympathy about that response that players were getting from the lottery, mainly because the lotteries all get accused by angry gamblers daily of being rigged.  So the handful of messages they might have received as a result of this drawing error were likely dwarfed by the daily onslaught of similar messages that do not have a shred of proof.  You really can't expect a customer service rep to sort all that out, and the result is a canned response, because most of the time what they replied is true.

The root problem is the computerized drawings.  This type of programming error has been shown to be quite common of the years. Someone types one letter wrong (e.g., akin to entering an "N" instead of a "Y" in the "allow duplicates" field) and the entire drawing is corrupted. And because these lottery tech companies obviously have no good monitoring system, the problems persist until enough human beings recognize the problem that it becomes obvious. Sometimes that takes months.

Meanwhile if some tech troll tries to make a false equivalent to ball drawings, they always point to that incident in Pennsylvania several decades ago. But that incident was easily discovered and actual disproves their theory because it was caught so easily.

The solution is ball drawings, but for some odd reason many lottery executives hate real drawings.

I don't get it. If I were a lottery executive, I would look at every ball drawing as a potential marketing event. They apparently look at them as annoyances.

An all-singles Pick 5 drawing has a huge player advantage. Why didn't you guys play it and say nothing and profit as long as possible? Let them figure it out when their "cheaper" RNG system actually costs them money instead of saving money.

It was but it wasn't so in state u spend  $252 and get back $425. Online u spend $252 and get back $750 but online numbers were sold out from the night before. Same in store with many of the numbers so you could be stuck out there not having every combination. Even b.s #'s sold out 24679. Many of us couldn't even take advantage you hadnumbers sold out 3-4 draws in advance. You only see that with quads and quints and 12345 not 47836 life wtf is that number being sold out.

dc lottery is one of those that limits how many of each combo can be sold, so if you don't manage to buy all the singles it's not risk free. and since so many people figured out they had a problem with the drawings, the singles were selling out fast.

YES they do! But also they see them (ball drawings)  as a added EXPENSE that they can cut.  In todays business world people get a bonus when they find ways to CUT costs.  Marketing for lotteries seems to have been cut across the board.  They just keep creating more expensive games (especially scratch offs) just putting out a press release for marketing.  Until sales drop they will not go back to ball drawings. 

Thanks again for doing what you do in contacting them! 

How long would this have gone on if Lottery Post did not step in??

We need the ball machine to be examined in NC. We recently had 9 consecutive doubles drawn and 14/16 overall. What are the odds of that? Seems unlikely to me

I' ve been saying for years now, that some drawing results don't agree with it's Data.. especially in Ga.  LOz have some yet undisclosed way of rigging even mechanical ball drawings,... So the Math says...

Good to see I'm not the only one calling out their BS ... Thanks to ALL for the Great work..!!

This does make you wonder what else is going on at the DC Lottery that hasn't been discovered yet.

DC Lottery - Deliberately Crooked Lottery?

Definitely Crooked Lottery?

JADELottery's avatarJADELottery

As we pointed out in the DC 5 Lottery needs to be audited immediately. The same thing that happened to Tennessee in 2007 Thread - https://www.lotterypost.com/thread/358919/8128587

This event just happened to occur at the same time as a promotion going on in April.

Coincidence?

I think their machines have a no win coding error too 🤣

The DC government is well known for being very incompetent across the board and that is one of the reasons it cannot get statehood.  A one traffic light town is more competent. 

A guy in my office was on DC unemployment comp for a month or two before he worked for my employer and got a threatening letter stating that he owed them $40 k. Lol. He tried a million ways to tell them that he received a few thousand in benefits but every rep there did not care. He had to bring in an attorney to meet with them before they admitted it was a "glitch" and backed down.

I know a couple of attorneys who handled workmen comp and other benefit type cases and every single time, DC would not pay when they lost and they had to walk into court again to get payment. I asked them if they thought it was intentional and was told that the DC government is just massively incompetent with no oversight.

So that likely extends to the DC lottery on some level. But they addressed the lottery issue quickly since it was a very public matter.

Oooh...you noticing those daily games too.😆

I thought I was the only one seeing those anomolies in the games here in Ontario. 

Surprise, surprise. Glad you're seeing it too!

Quick back story: I do a lot of paper betting and practicing for the Pick 2 games. Decided to do a back testing w/o tracking to see how often double digits (ex 11 55 88) hit over a specific period of time vs single digit pairs.

And to my surprise/not surprise, for a consecutive 40 draws - 20 days [March 11, 2026 to March 31, 2026] not a single double digit pair was played. Call it coincidence, luck of the draw, or whatever adjective which comes to mind but in my humble opinion that isn't "random" picks as far as I'm concerned. Since the full implementation of their so called PRNG system here in Ontario it's nothing but a dog's breakfast when it comes on to scoring a hit for ALL the daily games. And don't get me started on Pick 3 and/or Pick 4.

I have coined several hash tags in my whatsapp group for all 3 but the one i've used most often is #Repeating#isKing😄 simply because that's all that been happening with all three games. Need further proof - check Wed April 22 Pick 2 mdd and evd. Coincidence or just "random" #s selections? Hmm...you be the judge.

Btw i choose to zero in on Pick 2 because there are only 100 combinations in the pool so it's a bit easier to track its patterns and trends.

Needless to say I have other slogans/names I give to my Pick 3 and 4 workouts but that's another story for another day. 

Personally, knowing what I do know and based on how I've design my back testing work outs and "systems" to trigger when I should and shouldn't play it will take some real convincing for me that PRNG systems are better at digit selections for lottery games as oppose to mechanical ball machine picks. Of course, all lottery corporations would argue otherwise but we all know where their interest lies. 

Hopefully, someone in Olg's towers will come across this topic about Washington's DC 5 and the comments in this thread and do some further investigation as to why there are constant repeating single digit pairs in Pick 2 and repeating combos in Pick 3 and Pick 4 here in Ontario.
