The biggest unclaimed lottery prize in Texas was sold here at the South Shore Shell in League City.

In the past 5 years Texans have walked away from nearly $320 million in prizes. But the stores that sold these tickets still get paid their commission.

The largest single unclaimed payout was $7.56 million from a $12 million ticket sold Jan. 1, 2014, at South Shore Shell in League City. In Texas, after 180 days, unclaimed prize money reverts to the state.

But the shop that sold the winning ticket got its reward, a check for $121,385.34.

The total unclaimed amount for the state's financial year which ended Aug. 31, was $76.2 million.

This is the world's largest unclaimed ticket, a EuroMillions prize worth US$97.5 million.

 The world's largest unclaimed ticket was worth £63,837,543.60 (US$97.5M) had been bought by a player in the Stevenage and Hitchin area in UK. It is a world record unclaimed prize.

So what happens to unclaimed prizes?

In the USA, if the prize is not claimed within the time limit then the money goes back to the participating states.
