There are several collections you can choose, but the most efficient route is the Classic
collection. You can finish Classic without touching any other collection. Other collections require at least 340 stars to unlock all content, so you would need to partially play multiple collections.
If you get stuck, consult Zeming Jin's Classic YouTube playlist
. It contains every Hard and Expert challenges, along with a few Mediums. All credit goes to Zeming Jin for these excellent videos.Timed Challenge Trick
You can pause the clock by doing the following.
1. Swipe up on a touch screen or hit ESC.
2. Select Overview
at the bottom of the screen.
The clock is now paused. Do not select Continue
as you will lose all progress.
3. When you're ready to go again, select Cancel
All of Zeming Jin's videos finish with plenty of time, so now the timed challenges should be no problem.Free Cell Solver
Thanks to geodile42 for reminding me of this Free Cell Solver
. It should solve any Easy or Medium challenge causing you trouble. It did not work for some of the Hard or Expert challenges which required a solution in a low number of moves, since the default solver isn't that efficient. (Choosing the Short Solutions option always timed out for me.) I still had to use the videos for some Hard and Expert Free Cell.
Here's example input (from March 25). Note that T = 10. Each row corresponds to a column on the board. So in this example, the most buried card of the first column is the Jack of Spades and the top card is the Ace of Diamonds.

I don't know if there is a way to enter the partially solved challenges, but those tend to be marked Easy. I don't remember any of those giving me trouble.
