About Lottochaos & our method

Lottochaos is an independent statistics project about lotteries. We don't sell tips, we don't sell tickets and we don't promise wins. We show what the numbers really say.

Who runs it?

Lottochaos is run by a person with a PhD in mathematics and computer science who has worked independently in IT for many years. Analysing lottery draws is a long-standing hobby, driven by curiosity and a love of statistics, not by a "system" to sell.

Where does the data come from?

Results and prize breakdowns come from officially published sources.

Every draw is available as open data (CSV/JSON) so you can redo the calculations.

How do we calculate?

Odds and expected values are calculated exactly from the game rules (combinatorics), not estimated. For frequencies and patterns we use established tests such as the chi-squared test, corrected for multiple testing (Holm). Strategies are tested backwards on real draws (walk-forward backtest): each ticket only uses data known before that draw, and is compared with pure chance.

The result is always the same: every combination has exactly the same chance in every draw. Statistics can audit a lottery, but they cannot predict numbers. When we show "hot" or "overdue" numbers, that describes the past, not a forecast.

Independence

Lottochaos is not affiliated with any lottery operator or reseller. The project is funded by voluntary support (Ko-fi). Content comes from our own analyses; scientific studies are cited with their source in The science of chance.
