2D Lotto Number Groups
Splitting the 2D Lotto number line into five groups, the 15–21 group hit most often (14 hits over 20 draws), the 29–31 group least often (1).
The leader 15–21 sits 75% above the uniform expectation — with a perfectly even distribution each of the 5 groups would collect the same.
Groups (bins) are the 2D Lotto number line cut into equal ranges: the histogram shows how many hits landed in each. The slider changes the number of groups — from two (lower and upper halves) down to single-number bins — and clicking a table row selects the whole group on the play field. On the draw chart these same frequent ranges appear as bands where the lines thicken.

OpenQuestions About Number Groups
Which number group hits most often in 2D Lotto?
With a five-group split, the 15–21 range leads: 14 hits over the last 20 draws. The slider on this page recomputes the groups for any split, and on the draw chart this range shows up as a band of thickened lines.
What are number groups (bins)?
It is the lottery's number line cut into equal ranges — for example decades: 1–10, 11–20 and so on. The per-group frequency histogram shows which part of the line hits more often — a zoomed-out view of the same picture the frequency table gives for every single number.
Should I pick all numbers from one group?
A typical draw scatters across several groups, so a ticket from one narrow range looks atypical even though its odds equal any other. The current leader's skew is 75% above the uniform expectation — an ordinary fluctuation of randomness, not a pattern. How widely a draw covers the line is shown by the range breakdown.
How many groups should I set with the slider?
The standard splits are decades (10 numbers each) or five groups — easy to compare across draws. Two groups cut the line into lower and upper halves, and splitting down to one number turns the histogram into a plain frequency table. A similar binary breakdown by another trait is odd/even.
