# Placement Rules
### Definition
In order to keep competition fair, you can not randomly place anywhere within the [Binary Structure](/compensation-plan/business-logic/structures/binary-structure.md).\
This will be insured by certain rules that will be followed during all placement activity.
Here are the 2 Rules to follow:
* Placement is permanent, once placed it can not be changed.
* A user can only be placed at the end of your left or right [Placement Line](/compensation-plan/business-logic/structures/binary-structure/user-placement/placement-rules.md).
***
### Valid Placement
#### Valid Placement Example 1.1
Case:\
Valid placement for your very first placement.
or
#### Valid Placement Example 1.2
#### Valid Placement Example 2.1
Case:\
Valid placement for you if you already have a more sophisticated [Binary Structure](/compensation-plan/business-logic/structures/binary-structure.md):
or
#### Valid Placement Example 2.2
***
### Unavailable Placement
Case:\
Desired Placement Position is not available since it does not lay on the left or right [Placement Line](/compensation-plan/business-logic/structures/binary-structure/user-placement/placement-rules.md).
Below you see all possible placement positions for User4 marked green.\
Every other empty position that is marked red is not within your [Placement Lines](/compensation-plan/business-logic/structures/binary-structure/placement-line.md), meaning you can not place any users from your Holdingtank to that position.
