Autocorrelation of Спортлото «4 из 20» Мини: a statistical link between draws was detected. The lag-1 ACF of sums = 0.115; some lags step outside the 95% confidence band ±0.438 (lags checked: 6, significant: 1).Data includes draw #2337 of 18.08.2026.
The strongest link is at lag 4 (ACF=-0.461), stepping outside the confidence band ±0.438. A lone significant lag on a long series is often a false positive — worth re-checking with other randomness tests.
Autocorrelation (ACF) measures the linear dependence between draws separated by k steps (lags), on a scale from −1 to +1. A value beyond ±1.96/√n is statistically significant. Click a number in the table below to build its own correlogram.

OpenFrequently Asked Questions
Does the Спортлото «4 из 20» Мини lottery have “memory” — do draws depend on one another?
Across 6 lags checked, 1 came out significant. This may be a quirk of the sample or a false positive — lone significant lags on long series are not rare. Worth re-checking with other randomness tests.
Can a Спортлото «4 из 20» Мини draw be predicted from past results?
Autocorrelation tests exactly that possibility: if the ACF is close to zero, past draws do not help to linearly predict the next one. Non-linear links are searched for with transition probabilities and by analysing what follows a given number.
Markov chains What follows a number
What are a significant lag and a confidence interval?
Lag k is a shift of k draws back; the ACF shows the link between a draw and the one k steps earlier. The significance threshold is ±1.96/√n, where n is the number of draws: an ACF beyond that band means the link is unlikely to be chance (at 95% confidence).
Does autocorrelation confirm that Спортлото «4 из 20» Мини is random?
The absence of autocorrelation is a strong but not the only sign of randomness. The full picture comes from a runs test, frequency entropy and Benford’s law: if none of them find deviations, the draw is statistically indistinguishable from random.
How do I use autocorrelation to pick numbers?
You don’t, directly: it is a randomness diagnostic, not a number picker. If Спортлото «4 из 20» Мини draws are random (the usual case), every combination is equally likely, and it is easier to reach for the generator to get ready-made numbers.
