The most efficient way to complete this (by time spent actively playing) is by playing on those days. (Credit HolyHalfDead) Additionally, mentioned by several people in the comments, there's double XP days for certain games on seemingly random days. Meaning, it's the same xp/board, with the only downside being that you need to start up another game, which is by no means a big deal. This will still take many hours either way, but you can do it! Edit: You can also do two board Grandmaster Pyramid, as it gives 2/3 of the amount of three board. There's no videos or guides you can follow or anything for the solutions, as the boards are entirely random when you start the game. Do Expert Freecells if you're not very good at Pyramid or Grandmaster games in general.

So, in conclusion, Do 3 board Grandmaster Pyramids if you're confident in your ability to solve them relatively quickly. Expert freecell gives you about one sixth of a level every single time. 3 board Grandmaster Pyramid gives you a little over one level every single time you beat it. I could solve expert Freecells faster than Grandmaster Pyramids, but it is still much slower. If you're less confident in your ability to solve difficult boards, Freecell is better, though, it will take a lot longer. If you're able to solve the Grandmaster boards, 3 board Grandmaster Pyramid is definitely the best. I personally chose Pyramid, simply because it has a Grandmaster option and Freecell does not. The reason these two games are the best is because there's no hidden cards from the start.

I would recommend doing Freecell or Pyramid for this.
