Iowa Lottery officials are reminding people who bought holiday scratch tickets, or received them as gifts, to keep the nonwinners. They’re eligible for second chance prizes, but lottery spokesperson Mary Neubauer says you’ll need to act today.

The deadline to enter is at noon today. The drawing for the prizes will take place Tuesday and the winning numbers will be posted on the Iowa Lottery website. That website is also where serial numbers from nonwinning tickets are entered. Neubauer says the promotion offers 200 prizes of Sony electronics along with 10 cash prizes of $10,000.

Holders of the nonwinning tickets should wait to toss them out after checking the results of tomorrow’s drawing. Neubauer says tickets drawn must be presented to claim the bonus prize. Six different holiday themed instant scratch games were released by the Iowa Lottery this season. Different levels of prizes are involved for the various tickets.
