InstantMass estimates the odds of hitting each Massachusetts instant (scratch) game’s top prize as its ticket pool depletes. The overall odds of winning any prize are the Lottery’s official published figure; everything else — current/jackpot odds, edge, improvement vs launch, ticket-pool counts, and return-per-dollar — are our own estimates, derived from the Lottery’s published prize counts. They are best read as relative signals, not exact probabilities, and may be inaccurate or out of date (data is captured once daily). See the methodology.

InstantMass is an independent, unofficial project. It is not affiliated with, endorsed by, or operated by the Massachusetts State Lottery Commission. “Massachusetts Lottery,” game names, logos, and ticket images are the property of their respective owners; any such material (including the ticket images we cache and display) is used for identification and informational purposes only.

InstantMass is about the Massachusetts Lottery and is intended for users in the United States. Access is restricted by region — traffic from outside the US is blocked — and the site is not offered to, or directed at, users outside the United States.

InstantMass is provided for general information and entertainment. It is not gambling, financial, investment, or legal advice, and nothing here is a recommendation to buy any lottery ticket. Any decisions you make are your own, made at your own risk.

You must be 18 or older to play the Massachusetts Lottery. The lottery has a negative expected value — on average players lose money — and a game with “better” odds than at launch still has long odds. If gambling stops being fun or starts causing harm, call 1-800-GAMBLER.

InstantMass is provided “as is” and “as available,” without warranties of any kind, express or implied, including accuracy, completeness, or fitness for a particular purpose. The data may be wrong, incomplete, or stale. To the fullest extent permitted by law, InstantMass and its operator are not liable for any loss or damage arising from your use of (or reliance on) the site or its data.

We may change, suspend, or discontinue any part of the site or its data at any time, and may update these terms. Continued use after a change means you accept the updated terms; the “last updated” date above reflects the latest revision.
