Looks like I'm really bad at playing regular solitaire

You know that I cracked Mahjong Titans, a solitaire game.  tips here.

But on my computer, there's this regular solitaire that I fail 6 out of 7 times.
For as long as I can remember, my success percentage has stayed between 14% and 16% (Ok I don't remember going as high as 16 percent actually) and I've played it over 500 times.

How to improve my play at solitaire?

I don't think it used to be this bad on previous computers, I think I won more frequently then.
I mean, the solitaire I remember was just common sense: focus on the deep piles, don't get carried away with easy wins, plan for the future, try to balance your red and black tiles...
but now it seems more like tough, irreversible, luck.

Do I just have the hard version or something?

Meanwhile, I'll post more on Mahjong/Mahjonng titans later.  I sort of stopped playing it so frequently, discovered some new tips, probably lowered my win rate while experimenting wantonly with the thing...fun stuff.
