The average sum of 4/20 winning numbers over the last 20 draws: field 1: 40.7; the most common sum is 53, and all draws fell between 19 and 61. field 2: 44.6; the most common sum is 46, and all draws fell between 21 and 64. Data includes draw #1649 from 29.09.2026.
field 1: the lowest number of a draw averages 4.5 (most often 1), the highest averages 16 (most often 19). field 2: the lowest number of a draw averages 4.3 (most often 4), the highest averages 16.9 (most often 20).
The Min/Max/Sum table breaks every 4/20 draw into three values: the lowest and highest drawn number and the sum of all numbers. The summary cards above the table show averages, ranges and the most common values — handy for checking your own combination against a typical draw.

OpenMin, Max & Sum questions
What is the average sum of 4/20 winning numbers?
Over the loaded archive it is 40.7; the most common sum was 53, and the full spread ran from 19 to 61. How the sum moved from draw to draw is on the sum chart.
What is the ideal sum range for winning numbers?
The “ideal” range usually means the corridor most draws fall into: for 4/20 its centre sits near the median of 42. It guarantees nothing — every combination is equally likely, there are simply combinatorially more sums in the middle of the range. The sum generator can build combinations that land inside a chosen corridor.
Why look at the Min and Max of a draw?
They define a combination's spread: in 4/20 the lowest number averages 4.5 and the highest 16. A ticket with all numbers from one corner of the field produces atypical Min and Max — the table makes that visible at once. Full statistics of the extreme numbers are on the range page.
How do I use the table when picking numbers?
As a sanity filter: build a combination any way you like, work out its sum, minimum and maximum, and compare them with the summary. Landing inside the typical corridors means your ticket looks like most real draws. The sum distribution and transitions are in the extended analysis.
