Small sample: with fewer than 200 draws, big swings are normal and tell you very little.

Most sums cluster around the middle because there are far more ways to reach a middling total than an extreme one.

How to read this page

Reading it: Totals bunch up around the middle because there are many more ways to reach a middling total than an extreme one. Totals near the extremes (very low or very high) are rare.
What it can't tell you: Knowing the typical sum range tells you what past draws looked like, not which set of numbers will be drawn.

How Sum Distribution is calculated

This site does not guarantee winning. Lottery draws are random and past results do not predict future results. Every chart here describes the past. It cannot raise your chances of winning.
