Yes, at first play Poker Invaders looks like it is a pretty easy game but it works on all levels. That's the beauty of it.
We have professional poker players who are addicted to playing it and they have ridiculously high scores. But it is still simple enough to pick up and start playing without any poker experience.
Not everyone will find it so easy and sounds like you are pretty good at it so try getting a full combo of all the hands on level 1. That achievement will unlock huge bonus points (this is one key way that the top scorers on our leaderboards do it) and makes gameplay significantly more challenging.
