In the rules it clearly says you can play old games. More over it is very difficult to complete the task with new games as people at top of the game have few levels
I have completed 10004 levels. Ba;ance levels available are 21. Even if you add another 45 levels which will be released on Wednesday I cannot complete 110 levels. This is unfair for people who are at top of the candy crush. For many players who have thousands of levels you have given 30 levels.
