Frequently asked questions (FAQ)

Below you'll find answers to the most common questions. If something isn't clear, we explain most of it in more detail in the other articles.

Where does the data come from?

We use the official draw history of each lottery (Sportka, Šťastných 10 and Eurojackpot). The statistics are calculated from the complete history of all stored draws.

How often is the data updated?

The data is updated after new draws. You can see the date of the latest processed draw at the top of each game.

Is this site an official Sazka or Allwyn app?

No. It is an independent tool for the statistical analysis of historical draws. It is not an official application of Sazka a.s. or Allwyn.

Can statistics guarantee a win?

No. Statistics describe the past, not the future. Every draw is independent and no number-picking system increases the probability of winning the top prize.

What does the percentage next to each number mean?

The percentage is the share of a given number among all drawn balls in the selected range (how many times the number was drawn divided by the total number of drawn balls). It is not the probability that the number will come up in a single draw.

What are hot and cold numbers?

Hot numbers are those drawn most often in history, cold ones those drawn least often. It is a description of the past — it does not mean hot numbers will come up again.

Can I download the data for my own analysis?

Yes. For each game you'll find a button to download the complete draw history as a CSV file, which you can open in Excel and other spreadsheet editors.
