- Any Order
- Matching the winning digits regardless of their sequence. A box wager wins on any order of your selected digits.Related guide: Lottery Payouts Explained
- Average Gap
- The typical number of drawings between appearances of a particular digit, number, or pattern. DueDigits uses average gaps when calculating overdue ratios in its Gap Analysis.Related guide: How to Read the DueDigits Analytics

- Box
- A wager that wins when your selected digits are drawn in any order. A box on 417 wins on 417, 471, 714, 741, 147, or 174. Because several arrangements can win, box wagers generally pay less than straight.Related guide: Lottery Payouts Explained

- Independent Events
- Events whose outcomes do not affect one another. Every lottery drawing is independent, so previous results never change the probability of the next draw.Related guide: Lottery Odds Explained

Frequently asked questions
What does “box” mean in the lottery?
A box bet wins if your digits are drawn in any order, unlike a straight bet which requires the exact order.
What is a “due digit”?
A digit that hasn’t appeared in recent draws relative to the others. It describes the past record — it does not make the digit more likely to appear next.
What is a “mirror” number?
Each digit’s mirror is the digit five away from it (0↔5, 1↔6, 2↔7, 3↔8, 4↔9). A number’s mirror swaps every digit for its counterpart.
