Keno Delta Method — Number Difference Analysis
Delta method The Delta method for Keno lottery is an analytical tool that studies the differences between adjacent drawn numbers (sorted in ascending order).
Delta numbers reveal patterns in number distribution and help identify the most likely "distances" between numbers in winning combinations.
Based on the last 20 draws for Keno lottery, the most frequent delta values: Δ1 — 1 (5 times), Δ2 — 1 (7 times), Δ3 — 1 (8 times), Δ4 — 1 (8 times), Δ5 — 1 (8 times), Δ6 — 2 (6 times), Δ7 — 1 (8 times), Δ8 — 1 (7 times), Δ9 — 1 (5 times), Δ10 — 2 (7 times), Δ11 — 3 (8 times), Δ12 — 3 (6 times), Δ13 — 1 (11 times), Δ14 — 2 (5 times), Δ15 — 1 (6 times), Δ16 — 3 (5 times), Δ17 — 1 (6 times), Δ18 — 1 (7 times), Δ19 — 3 (5 times).

How to Use the Delta Method for Keno
Study the delta tables
Identify the most frequently occurring differences for each position. These values show the typical "distance" between numbers.
Choose a starting number
Determine the first number of your combination based on frequency analysis or other methods.
Add deltas
Sequentially add the most frequent delta values to the starting number to get the remaining numbers of your combination.
Advantages of the Delta Method for Keno
Reveals structure
The method shows the internal structure of winning combinations — how the distances between numbers are distributed.
Filtering
Allows you to filter out combinations with atypical distances between numbers, focusing on more probable options.
Combinability
The Delta method works excellently with other analysis methods for creating balanced combinations.
