Paniting bricks,test case

This is the following details i have got regarding a project to develop ,can someone help me to understand it what to do ...

Intent: User can paint brick in his/her city wall with caption, message and dedicate to someone.
User can only edit his/her brick.

Anyone can read content of brick.
Anyone can comment on it.

Use cases:

Brick: Every country has n number of cities and every city can have 1 to n number of walls.
1 wall can have max of 90 bricks. 2nd wall would be only initiated once all bricks of 1st wall will be occupied.

A brick can be only owned by a single guy..

When owner visits on his/her city wall then his brick should animate.

Need to find out total number of walls initiated, total number of bricks initiated in specific wall.

Admin can edit any brick whereas user can edit only his/her brick.

If more than 10 bricks would be flagged then brick would be in invisible mode.


Thanks in advance .........
