Why do we study winning numbers history?

The goal of betting is to find the winning combination of numbers. One of the most common strategies is to select a set of numbers larger than the count of winning numbers being drawn and then create tickets covering all or the most of combinations of these numbers. Majority of Expert Lotto features will help you in doing so.

However in this part of the application we are trying to use a different strategy. The strategy is based on evaluation of frequency of number occurrences in the lottery history.

To understand this strategy you should be familiar with Winning Numbers History page.

Expert Lotto presents the winning numbers arranged in tables and provides simple functions and visual tools helping you to estimate the future values in Winning Numbers History tables. Your estimates then provide input parameters for Winning Numbers History filter. If you manage to fit your estimates into +10 and -10 error margin from the actual value then your can reduce the list of all possible tickets (almost 14 million tickets in lotteries drawing 6 numbers from a pool of 49 numbers) in such a way that the resulting set contains tens to hundreds tickets. However this resulting set is guaranteed to contain the Jackpot winning ticket.

 

Example [Expert Lotto 6/49]

  1. Write down the last two draws from Winning Numbers page (28/2009 1st Wed a 2nd Wed). The tickets used in this example are:
    16,18,22,23,28,29 (28/2009 1st Wed)
    and
    2,13,16,17,25,40 (28/2009 2nd Wed)

  2. Switch to WN History page. Make sure that options 1.st Wed, 2nd Wed. and 1stSun, 2nd Sun as well as All Draws are selected and click Update button. The data in the table are updated. Click the header of column labeled "0" to sort the numbers in ascending order according to their occurrences in the winning numbers history.



    Numbers 2,13,16,17,25 and 40 are given as the latest draw with the history period "1". The sum values in Summary Table are as follows:


    Write these values down, you will need them in following steps. These values are automatically provided in the Winning Numbers History filter. Also note the values in the Summary Table page. In this case the values are:
    368,746,1202,1646,2008,2407,2773,3154,3500,3867,4241
  3. Select Edit in the Winning Numbers menu. Click Hide box in the row for the 2nd Wed 28/2009 draw. The record will change as follows (see the highlighted ticket):



    Note:
    Should you wish to repeat the exactly same example then you must skip all recent draws.
  4. Switch to Winning Number History page and press button Update. The table is recalculated as if the 2nd Wed 28/2009 draw has not been made yet.
  5. Go to Ticket Generator and select Ticket Numbers range 1 to 49, check option Generate maximum possible number of tickets and then click OK. The maximum possible count of tickets 13 983 816 is loaded into the package.
  6. Select filter Winning Numbers History and enter the sum values you wrote down earlier into appropriate table cells while adding 10 in the Max column and subtracting 10 in the Min column.
    Note: Make sure you are entering values into the table in Sums tab.
    The filter window should look like follows:



    Fields 1st.Wed, 2nd Wed, 1st Sun, 2nd Sun are options for winning numbers selection. All checkboxes to the left of History Index column must be selected. Select And as the Logical Condition. Also select Leave in the Matching Tickets panel. Now click button Apply.
    The tickets in the package are backed up first and then you will see filter's progress bar showing the number of tickets processed so far. Because of the large number of tickets being processed this task is very time consuming, especially on slow PCs.

  7. When the filtering is finished you will get a message how many tickets are left in the package as well as how many tickets were removed from the package. In this case the number of tickets left in the package is 196. These remaining tickets always contain the Jackpot winning ticket (2,13,16,17,25,40 in this example).
  8. To verify this switch to Visual Package page and click the winning numbers on the panel (right hand side). The numbers are highlighted in table's header. The last table column shows the match with the Jackpot winning ticket. (The ticket with blue background in the figure below)



    Note:
    Only tickets matching the winning numbers in 5 or 6 numbers were left in the package. The Jackpot winning ticket has blue background.

    All 196 tickets in the package met filter settings (error margin +/-10 from the expected sums in each column). After using option Remove Match in (see figure above) the ticket you were looking for remains in the package.
  9. As the last step in this example you must edit the winning numbers database again. Select function Edit in Winning Numbers menu and switch option Show skipped entries. Remove the "Skip" flag of the winning ticket to restore the winning numbers database record.

Notes

  1. The number of tickets in the package can be reduced even more. When evaluating entries in the Summary Table you can see that quite frequently the differences in 3 to 5 columns are lower or equal to +/-10. Then the filter settings should change as follows:



    As you can see additional filter condition is defined:

    This condition requires that in any of 3 to 5 columns the difference between the last known sum value and the expected sum value is to be at most between -10 to +10. Usually the number of tickets left in the package is higher (in the order of hundreds).
  2. Winning Numbers History page offers other supporting tools helping you to determine more accurate filter parameters, e.g. you can evaluate Differences Chart for more accurate ranges of sum differences in each column.
  3. You can also reduce the package contents by using functions from History Differences tab.
  4. This function can be used for a selected draw(s) in a week only. In the example below the function will process the 2nd Wednesday draws only:
     
    However in this case you must also change all values used in the procedure - sums, tables with history of numbers, charts etc.
  5. When using these functions for other lotteries and/or other winning numbers periods, you must realize that the values of sums, ranges, count of the latest draws, number of tickets left in the package etc. will differ from the example provided above! However the function principle does not change and it always provides a small set of tickets containing the Jackpot winning ticket.

Notes:

  1. The setting for margins to +/- 10 is recommended only. You can change these values in any way. The wider margins the more tickets are left in the package after filtering.
  2. Min/Max settings in the rows of Winning Numbers History filter need not be identical. Some margins can be left wider and you can omit some margins at all.
  3. By checking option At least "xx" to "yy" columns must pass you choose the minimum and maximum count of columns that must meet filter conditions. This applies to any combination of columns. The resulting sums (use button Lookup Min & Max Ranges to look them up ) will not match your original estimated margins but they should be wider. This option is suitable when we expect mistakes in our estimates because the tickets left in the package will still contain the Jackpot winning ticket you are looking for. The larger the difference between "x" and "y" the more tickets will remaining in the package after filtering.
  4. The program remembers the last used settings for margins in this filter.
  5. Check that your selection of winning numbers matches the one from Winning Numbers History page before filtration and always use Update Sums button to refresh the table in filter window.
