After you've installed PUArcade for Mambo, sometimes it isn't obvious how to actually get to the component to use it.  While it is a standard Joomla procedure, it isn't very intuitive for new joomlers.  Read on for a step by step explanation of how to actually publish and get to PUArcade after you've installed it.   Note that this procedure can also be used for most other Joomla components as well.

1. Login to your Joomla administrative area.  This will be located at
www.yoursite.com/administrator.

2. Mouse over "Menu" in the menu at the top of the admin interface. 
From the dropdown box that opens, select the menu that you want to add a link to PUArcade in. 
This might be something like "mainmenu" or "usermenu", as shown in the image below.

3. Click the "New" button as shown in the image below.

4. Select "component" from the "components" section, as shown in the image below,
then click Next.

5. In the screen that comes up, give the link a name. 
"PU Arcade" or "Games" are common examples.
Select "PU Arcade" from the list of available components.

6. Make sure "Top" is selected as the parent item.

7. Make sure "Yes" is selected for "published:"

8. Make sure "public" is selected for "access level".

9. Click "Save"

Now, view your site, and you should have a link to PUArcade. 
Clicking on it will bring up the game selection page. 

Good Luck!  Comment below if you have any questions.
