About Lottoeule

Lottoeule answers a very specific question: How much would you have won or lost if you'd played the same German Lotto 6aus49 numbers every week since 9 October 1955? We also calculate what would have happened if you'd put the same money into an ETF savings plan instead. Both with real data, no esoterics, no sales gimmicks.

Who we are

Behind Lottoeule is Kapierstau Development UG (haftungsbeschränkt) based in Bernau near Berlin, Germany. We are not a lottery operator, not a bank, not financial advisors. We like data and believe that publicly available lottery numbers and freely available market data are enough to finally answer an old question with facts.

Full provider information is in the imprint. Data processing and tracking are disclosed in the privacy policy.

What we actually do

  • We calculate. Picks against every single draw since 1955. A combo from 1956 is scored against 1956 quotes, not today's. DM/EUR conversion and stake adjustments over the decades. No estimates.
  • We compare. The same total stake invested in a broad ETF savings plan over the same period, using historical S&P 500 Total Return data.
  • We explain. Probabilities, myths like "hot numbers", prize-quote optimization. Including uncomfortable findings.

Where the data comes from

  • Lottery numbers and prize quotes come straight from lotto.de, the official site of the German lottery association DLTB. We only use the main Wednesday and Saturday draws.
  • S&P 500 performance comes from a public Total Return dataset (Robert Shiller, Yale, plus more recent monthly sources).
  • Probabilities and comparisons are sourced from reliable publications cited in each article. Example: NOAA for lightning-strike risk, Tulane University for asteroid-impact risk.

Images and illustrations

Every image on this site, the owl logo, the OG preview images and all article illustrations, was created with the help of AI image generators. We provide the description, the owl is rendered in the generator.

The images illustrate, they do not document. Where we show numbers, data or historical events, the values come from the primary sources we name below. Not from the images.

Sources & references

So our claims stay verifiable, here are the external primary sources our articles rely on. Individual articles link directly to this section at the relevant points.

What we don't do

  • No play recommendations.
  • We don't sell or broker lottery tickets.
  • No trackers beyond anonymous reach measurement (self-hosted Umami).
  • No storing personal data without clear cause.
