Big Sky Bonus

Big Sky Bonus is a daily Montana Lottery game with big odds of winning!

The starting jackpot is a guaranteed $2,000 and is progressive, so it keeps increasing until someone wins. The cost per play is $2.00 and you can play up to five times on one playslip.

To play, choose four numbers from 1 to 28 (white balls) and one Big Sky Bonus number from 1 to 17. You can pick your favorite numbers or have Quick Pick randomly generate them for you.

You win the jackpot if you match all four regular numbers (white balls). If you match the Big Sky Bonus number, it's worth an extra $10.

Draws take place daily at 7:30 PM Mountain Time. Tickets may be purchased up to two minutes before the drawing (7:28 PM). The Multiple Draws option lets you play up to seven consecutive drawings.

The overall odds of winning a prize are 1 in 6.92.

The set prize amounts are based on the expected number of winners sharing the prize pool. However, if the number of winners and the available prize pool varies, set prizes may be paid on a parimutuel basis and may be lower than stated.

Winners who don't provide a Social Security number or are not U.S. citizens are subject to higher tax withholding rates and will receive less than the advertised jackpot amount.
