Big Sky Bonus

Big Sky Bonus is a daily Montana Lottery game with great odds of winning! The jackpot is progressive, so it keeps increasing until someone wins. The cost per play is $2.00 and there are four prize tiers in total.

Draws take place every evening at 7:30 PM Mountain Time. Tickets may be purchased up to two minutes before the drawing (7:28 PM).

How to Play

To play, choose four white ball numbers from 1 to 31 and one Big Sky Bonus ball number from 1 to 16. Pick your favorite numbers or have Quick Pick randomly generate them for you. You can play up to five times on one playslip; each panel is one entry.

Choose the Multiple Draws option to play your lucky numbers for up to seven consecutive drawings.

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.

The overall odds of winning a prize are some of the best in the state at 1 in 7.79.

Prizes and Odds of Winning Big Sky Bonus
