What is Package?

Package is some sort of storage locker which keeps the tickets you are currently working with. It is the place where you for example load the tickets to check if you won anything in the previous draw. The Package can hold a full wheel of all possible combinations which can be filtered down to an affordable number of tickets. The Package lets you check the win guarantee of a wheel you've downloaded from internet. You can save the tickets in the Package to a file to share them with your friends. You can print Package tickets directly to paper playslips etc. There are many application features dedicated to working with Package tickets.

There are several different views available to see tickets in the Package :

• Plain table - the Package content is presented as a table where each row is a single ticket and table columns contain ticket numbers.
• Matrix - is a table showing all pool numbers in various layouts and how tickets numbers fall into the selected layout.
• Statistical properties - shows Package tickets in a table together with some statistical properties like the ratio of odd/even ticket numbers, the sum of ticket numbers etc.
• Winnings - shows a table of tickets and the count of ticket's winnings for selected range of past draws.

You can fill the Package from different sources:

• Custom number combinations - enter ticket numbers using keyboard.
• Ticket file - load tickets from a text file or CSV file (e.g. when downloading a wheel from internet). Or open a ticket file in Expert Lotto's disk space saving binary format.
• Combinations of randomly generated numbers.
• Generate a full wheel listing all possible combinations of selected numbers.

 When inserting tickets into the Package you can combine them with the current Package contents in several ways - just click the little down arrow on Insert button:

• Insert - the default action - replaces the current Package contents with the new tickets.
• Append - adds the new tickets to the end of current Package contents. This may lead to the duplication of some tickets. Click menu Package - Remove Duplicates to ensure that each ticket is present in the Package only once.
• Merge - combines the new tickets with the current Package contents to avoid creation of duplicated tickets.
• Remove - removes the new tickets from the current Package contents.

It is possible to revert all Package operations using Undo/Redo actions. For example when you see that a filter you've just applied removed too many tickets, click menu Edit - Undo to restore tickets in the Package into the same state as before running the filter. Then you can use the filter again with different settings.

To remove all tickets from the Package click menu Package - Clear.

 When a Package operation is finished you can see how many tickets were removed/added/filtered out on application's status line at the bottom of the main application window.

 The Package content is restored after application restart and also when switching to/from a different lottery.
