    Circles

    Can you position all of the 9 different circles in the following 3x3 grid in accordance with the 7 statements bellow (it is possible)?



    #1. All of the spotted circles each occupy a corner position.
    #2. The plain red circle and the striped red circle are in the same column.
    #3. The spotted red circle is one position bellow the striped green circle.
    #4. The plain blue circle is one position above the plain red circle.
    #5. The spotted blue circle and striped blue circle are in the same column.
    #6. The striped blue circle is in the top row.
    #7. The plain green circle is somewhere to the right of the plain blue circle in the same row.

    Additional comment: all the circles must occupy a position in the grid with no more then one circle in any one position.

    Here is the solution
    I hope I didn't make any careless mistake...

    Attached is the Excel document with the steps


    Edit : I forgot to put the meaning...
    1st letter :
    - S = spotted
    - T = striped
    - P = plain

    2nd letter :
    - R = red
    - B = blue
    - G = green
