We probe the internet for official results from all major lotteries, and pull the data from the most recent draws and populate our databases, so we are constantly up-to-date with our data. Although our information is up to date, please view our disclaimer. However, even the official websites have disclaimers stating along the lines of "In the event of any discrepancy between this information and the official information of {lottery site}, the latter shall prevail." Since there is a possibility of error from the lottery sites in posting data, our processes will re-poll sites and post any updated information, updating our databases in the process.
Some lotteries have come to an end. Actually most of the ones which appear to have ended only went through a name change. A couple of examples of some National lotteries are:
- In Canada, Super 7 became LottoMax.
- In the US, The Big Game became MegaMillions
Not to worry, we have the results from all the older lotteries as well.
Lotteries may have changed throughout the years. For example, the Powerball Lottery in the US has changed 6 times since the beginning, with a different amount of balls being loaded into the drums. Some lotteries changed the frequency of their draws, from once a week, to twice a week. But our databases take all changes into consideration, and we treat each change as a unique instance for that lottery. This allows us to provide you with proper summaries and statistics for each lottery.
Many of the official websites for the lotteries do not have any results going back more than 1 year. This makes sense from their perspective because a potential winner may have up to 1 year to claim their prize(s). Lottodatabase.com is different. We have a complete collection of draws for each lottery right from when that lottery started. It is searchable, with statistics and analytics performed against the data.
Where possible, we pulled the information from the lottery's home site. Some of these sites have draw information going back to the beginning of the first draw. Other sources include going "back in time". Sounds like science fiction, but there is a site called Internet Archive: Wayback Machine which stores snapshots of websites going back in history. This was very handy in creating the data for this website.
