spider question

[Gerardo Rodriguez]

Hello, good morning,

Thank you very much for developing kpatience, in particular spider, 
which I normally play.

I see at the top of the different games a number of approximately 10 
digits, and the question is this, are the plays predetermined or are 
they created randomly each time the game starts?

I really like version 2 (medium) of spider, and I have already won 977 
games without losing any, and I would like to know if I have won games 
made at random or designed so that in some way they can be won.

Thank you so much,

Gerardo
