Ehh.

I tried both "Speed Fiend" and "Speed Free" and find that I like this one slightly better only because Speed Free has a lot of glitches. With this one, you drag and drop the cards while on the other, you have to repetitively tap the screen.

The cons are that they dont give you the option of playing double cards and the hardest level.. isnt that hard at all.
