Statistical note
Every valid six-number line has the same chance in a fair draw. Differences in historical counts are expected random variation.
First Division: 1 in 3,838,380 per line · Powerball is 1 in 10 conditional on the Lotto line.
Frequency analysis
Observed history compared with the equal-frequency expectation.
Powerball frequency

“Hot” and “cold” are historical labels only. They do not change the probability of the next draw.
Pairs & triplets
Repeated groups in the archive, with practical expected counts.
Repeated historical pairs and triplets do not predict future draws.

Random line generator
Uniform random selection with optional human-pattern filters.
Your lines
Choose your options and generate 1–20 lines.
These filters do not improve draw probability. Avoiding common human-picked patterns may reduce prize sharing if a line wins.
