Look for your Jazz2 folder (For instance C:\games\Jazz2), and extract the levels into that folder. Easy. After you're done you can see the levels in the "Home Cooked Levels" list.

It can be possible that levels don't appear in that list, there's two reasons for that:

1. The author checked the "Hide in Home-Cooked levels list"
2. The list is full (the limit is 256 levels)

Either case, open Windows Explorer and go to your Jazz2 folder. Look for the level you want to play, click it and hold the button, then drag the level over the Jazz2.exe file.
