Understanding Regular and Golden Numbers

What the five regular balls and the golden ball mean, and exactly how every derived judgment is calculated.

Every Golden Ball round publishes six numbers: five regular balls and one golden ball. Everything else you see in a result row — Sum, Odd/Even, Under/Over, Size — is derived from those six numbers by fixed rules. This guide states each rule exactly, so you can recompute any judgment yourself.

The regular balls (1–28)

Five balls are drawn from a 1–28 pool and displayed in generation order. Their sum is the basis of three judgments. Because the smallest possible sum is 15 and the largest is 130, every boundary below is fixed forever:

Sum — the total of the five regular balls (range 15–130).
Odd/Even — the parity of the sum.
Under/Over — Under when the sum is 72 or less; Over from 73 upward.
Size — Small for 15–64, Medium for 65–80, Large for 81–130.

The golden ball (0–9)

One golden ball is drawn from 0–9. It has two judgments of its own: Odd/Even is the parity of the digit, and Under/Over is Under for 0–4 and Over for 5–9. The golden ball never participates in the regular-ball sum.

Why the site recomputes judgments

The Community does not blindly trust judgment labels: it recomputes every judgment from the published balls and rejects a round whose labels disagree with its own numbers. A result row can therefore never show a sum or judgment that contradicts the balls beside it.

This is a simple platform rule: data that does not add up is withheld, never displayed with a shrug. What reaches your screen has passed that arithmetic check.

Reading a row at a glance

A practical habit: read the five regular balls first, confirm the sum feels right, then glance at the three regular judgments together — they always move as a set. The golden ball’s two judgments stand alone. After a few rounds the whole row reads in about a second.
