Hi Ionut, I like the changes you have made from your previous concept. Here is what i think of each one:
(1) It looks very amateurish, the text having a background color makes it harder for viewers of this logo to read and it won't be able to cross over cleanly on different forms of media like the other two.
(2) I like this design. It is clean, clear and has cross over appeal unlike #1. My problems with it are that poker and plus should be spaced out a little more and, like Luke mentioned, the red spade should be the same height as the rest of the text.
(3) This is by far the best and most unique design out of the three. It has all the good qualities of #2 and more.

thanks Jamal, very helpful again :).
