Across the last 20 6D Lotto draws, number 1 (field 3) has the longest current drought — missing in 20 of 20 consecutive draws; the longest active streak belongs to number 6 (field 1), hitting in 1 of 20 consecutive draws.
The Wald–Wolfowitz test flags |Z| ≥ 1.96 for 3 of 60 numbers — on a sample of 20 draws such isolated outliers are expected and are not evidence of manipulation.
Runs analysis tracks continuous sequences of identical outcomes: a streak means a number hit several draws in a row, a drought means it missed just as many in a row. The Wald–Wolfowitz test compares the actual count of such runs with the count expected for a random sequence.
Z = (R − E[R]) / σR, E[R] = 2n₁n₂/N + 1
How the Z-statistic is computed for each number:
- R — the actual number of runs: continuous hit/miss stretches in the draw history;
- n₁ — draws where the number hit; n₂ — draws where it missed; N = n₁ + n₂ — sample size;
- σ_R — the standard deviation of the run count: √(2n₁n₂(2n₁n₂ − N) / (N²(N − 1)));
- with |Z| < 1.96 the sequence is considered random (significance level 0.05).

OpenQuestions about 6D Lotto Streaks and Droughts
What is a runs test?
A statistical method that studies runs — continuous sequences of identical outcomes. For a lottery these are hit streaks (a number drawn several draws in a row) and droughts (a number missing just as many draws in a row). The method answers whether these alternations look random.
What is the Wald–Wolfowitz test?
A classic randomness test for a binary sequence. It counts the actual number of runs R and compares it with the value expected for a random sequence, E[R] = 2n₁n₂/N + 1. The deviation is expressed as a Z-statistic: the further Z is from zero, the less random the sequence looks.
What does the Z-statistic mean in a runs test?
Z is the actual number of runs minus the expected number, divided by the standard deviation. |Z| > 1.96 means the sequence is non-random with 95% confidence: positive Z — alternation is too frequent, negative Z — continuous runs are too long.
Should I bet on numbers with a long drought?
A drought does not raise a number’s probability — every draw is independent, and in a fair lottery the test confirms it. But as a selection system runs analysis works: if you prefer picking numbers by statistics rather than at random, mark the numbers with interesting runs in the table — a click adds them to the combination generator on this very page.
Is the 6D Lotto lottery random?
The runs test is one of the standard ways to check: it catches both overly long runs and suspiciously frequent alternation. For the full picture see autocorrelation (memory between draws) and the Pearson χ² test (bias of individual number frequencies) — links in the Where to next block.
