A {{Userbox}} (or User Template) is something that is placed on your userpage to describe yourself in some way. Here you can find a list of userboxes available for Bloons Wiki. (This page can be found under Userboxes of the Miscellaneous tab of the Bloons Wiki navigation bar.)
On this page, user templates (userboxes) are mostly shown in their generic form only, however many of the userboxes can be customized via parameters: {{User Template|parameter}}. If you open any link under the Code of template column in the tables below, you will see more information how to use the corresponding template include its parameters available.
A parameter marked by the < and the > characters (e.g. <rank number>) only refers to a label of the parameter. Thus, it should be replaced it by a real value when adding ther userbox to your userpage (without the < and the > characters).
Example:
You want to use a {{User Rank}} template on your userpage and you are rank 62 in BTD4. The template says: {{User Rank|<rank number>|BTD4}}, so you put a {{User Rank|62|BTD4}} code to your userpage.
If you want to add any code to your userpage, for example you want to copy & paste a code from this page, then it is recommended to switch your userpage to the Source mode while editing, before you paste/add the code to the page.
If you choose your gender in Preferences (My Info → Basic information → My gender), userboxes will recognize it only if the userbox is put to your userpage (so don't expect to see the result on this page)
Formatting/grouping of userboxes
Typical usage with unwanted side effect
If you want to use more userboxes together, you can do it as following:
The userboxes are grouped together automatically (number of columns depends on your screen resolution). However, the automatic grouping have an unwanted effect for any text that follows the userboxes:
Correct formatting
To prevent the problem above, you can use the following code:
Please, if you plan to state anything not usable for most of the community ("This user likes parrots", "This user wants to be a brain surgeon", …), then use the option I want to create my personal userbox (which uses User: namespace under your userpage instead of Template: namespace for public templates). You can also use a custom userbox on your userpage, especially if you are not experienced with Wiki markup.
First enter the full title of the template's name into the box (i.e. Special:Mypage/My userbox), then click the "Create userbox" button. Special:Mypage will be replaced by User:visitor automatically, so keep the format of the name like Special:Mypage/foo for User:visitor/foo.
Create a userbox like "This user likes/dislikes/loves some game" where people can show their relation to the particular game by values 1-3, such as: {{User Bloons1}}, {{User Bloons Supermonkey}}, {{User BTD5}}
