Cannot be done in challenges. Play 100 games accumulative between the two modes. I had 93 tri-peaks boards cleared, and 7 pyramid board clears.
The solution says "OR" but it must mean all together.
For the King of the Hill achievement of winning 100 Klondike, spider, or free cell games, this didn't work. I needed 100 free cell wins. ( I used DrCanadianNinja's guide)
