About Bits & Odds

Bits & Odds publishes free, independent analysis of publicly released lottery data. Every number on this site is computed from figures the state lotteries publish themselves, recomputed every day, with the formulas written down.

What we actually do

Every state lottery publishes how many prizes each scratcher started with and how many are left. Almost nobody reads it, because it is buried, inconsistent between states, and meaningless without arithmetic. We read all of it, every day, for 26 states and 1,615 games on sale, and turn it into the only question worth asking: how much of a dollar comes back on this ticket, right now.

For draw games — Powerball, Mega Millions and the state games of Arizona, California, Colorado, Delaware, District of Columbia, Florida, Georgia, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Jersey, New York, North Carolina, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Texas, Vermont, Virginia, Washington and Wisconsin — we do the same with the draw histories: how often every number has come up, how that compares with what it should be, and what a ticket is actually worth.

That is 41 states in all: some for scratchers, some for winning numbers, most for both. Which ones, and what we hold for each.

How to check us

• Methodology — every formula, including the ones with known weaknesses, and what those weaknesses are.
• Sources — the official page or feed behind every state and every game, when it was last read, and a list of every place where two official sources disagreed with each other.

Draw results are cross-checked against several independent official feeds before publication. That is not a formality: New York’s open-data feed is missing six Powerball draws, including the record $2.04 billion drawing, and publishes two Mega Millions draws with the wrong numbers. All of it is listed on the sources page.

What we will not do

Nothing here is paywalled. Several sites in this niche charge for the metric that matters most; ours are all free, and we intend to keep it that way.

We do not sell tickets or take bets. We are not affiliated with any state lottery. Our video poker and blackjack pages carry offers from online casinos, and our video poker practice pages carry one from VideoPoker.com, a free-play site. Each is marked as an ad. If you sign up through one we may earn a commission. The offers never change a number on this site.

We do not claim to beat the lottery. We publish which tickets return more than others — not a system, not a prediction, and no suggestion that a number is ever “due”. Where the honest answer to a popular question is that a pattern is not real, we say that, and show the working. Every game on this site has a negative expected value; that is what a lottery is.

Who publishes this

Bits & Odds is published by Voitto Virta LLC. The site began in 2019 as a spreadsheet tracking California scratcher odds and is now an automated pipeline that reads the official sources every day and rebuilds the site from them.

Media and data enquiries, corrections, or a state you would like added: get in touch. If a figure here disagrees with the official lottery page, the official page is right and we want to know.

Some reading we like

The stories that got us interested in the first place: Jerry and Marge Selbee, a retired couple who found a positive-expectation window in the Michigan lottery and played it legally for years, and the MIT Blackjack Team. On risk and decision-making generally, Nate Silver’s On the Edge: The Art of Risking Everything is worth the time.
