Here is your guide to club penguin. First of all you should become a member because with the benifits of a member you are able to buy stuff and do not have to live off of free items during events. The best way to raise your popularity is make a lot of freinds (the limit is 100), throw a lot of partys, waddle around and have fun, but you should always redo your igloo once a month like I do.
There are a few rooms that are hard to get to like the dojo, the PSA and the EPF rooms. for the dojo you need to go up to the mountain and then your in the courtyard it's usually crowded because so many people like to play the game. The PSA room (or HQ) is easy to get to, but you need to be 30 days old to go in. The EPF is a bit harder you need to buy the game Elite Penguin Force and enter the code then you get access to the room, but there is almost no one in there except you.
There are many games, but a few don't get you any coins at all. the one that doesn't get you any coins at all is the ninjutsu game at the dojo. As I said earlier it is kind of hard to get in so don't really get your hopes up, but you get exp from it and when you do that you can level up in the belt. When you reach black belt you get to (if you're a member) buy a outfit and have access to the super secret clubhouse. It's really hard to beat Sensai but is easier if you have special cards that you can buy at a few stores. You get to play as many games as you want. All the other games get you coins. They are Hydro Hopper, Jet Pack Adventure, Cart Surfing, Surfing, and Tube Racing. The best game to get coins (and the shortest) is Cart Surfing.
So try it and waddle around and have some fun!!!
