To check your odds for a game you decided on several parameters such as the method of making tickets set, the number of games, etc. and then you see the result of playing the lottery game based on the previous games. 

"Try again" remembers all those settings so that makes a new set of tickets, and plays it against the same number of games and shows you the new result all in one click!

Try again doesn't work for system 8 because, with the same 8 numbers provided by the user, the same tickets set will be generated.  

There are some basic information and also the number of tries on the Tryn again button for more visibility.

On this page, you can export the last series of tickets if you want to.
