Just keep playing the game and you'll get to level 60 in no time.
Tips:
-Higher stake saloons gives decent XP
-Free spins enables double XP
-Spin and play gives XP for 1st, 2nd and 3rd place
-Poker shacks gives little XP

Note that you gain experience by winning hands, its recommended you play on a tables that can hold many players.




The Achievement levels go from Level 3 all the way to Level 60.

You can get this either by playing allot(kinda developing a gambling problem), or later on in game when you get allot of chips, you go back to low chip tables and farm "newbies".
Be WARNED, you'll have hard time finding a table that does not have a multi billion/trillion guy that is there to do the same thing.



The number of hands you require to win in order to get all the achievements listed above go from 10, all the way to 50,000 hands won.

NOTE You can combine this trick and the one below "Hands" in order to win hands even faster.

If you haven't yet got a win on all the hand combinations there is in the game, you can go to lower chip tables and start multiple sessions, that way you make it much faster and easier, that is of course if you manage to keep up with all the tables and fast playstyles.
