*EDIT: There have been reports that this no longer works as of the most recent update. I am leaving the solution up in case it becomes viable again, but I would recommend against getting your hopes up. The steps outlined in the solution are fairly easy, so feel free to give it a try if you don't believe the reports I've received so far.
This achievement is very easy if you have access to the Android or iOS versions of the game. If you can confirm this works on another platform or device please let me know, and I will gladly update this solution!
All you need to do is win a game, and when you are on the "Congratulations!" screen (where you can choose "New game" or "Home") just exit by quitting the app. Re-open the game, wait for the login and sync to finish (the spinning icon in the top corner), then select Spider on the Menu. It will show the finished game, re-fire the fireworks, and take you to the "Congratulations!" screen again. Repeat until you have enough wins.
This strategy works for most of the "complete games" achievements for Klondike, Spider, and Freecell (see the list below)!
