Create new fields in a matrix

I'm afraid that the method posted has very little flexibility with regards to conditional formatting since the values all come from one measure. A little can be done, but not what you are after:

The good news is that there is another method which will allow for CF. Basically it entails using the recently included field parameters functionality, althoug there are some tradeoffs.

Firstly, delete the 'Matrix Columns' table.

To change the order of the financial periods in the matrix, you need to change the order value in the Dim Period table:

 Sort the table by the Order fields in ascending order; then sort the dFinancial Year column by the Order column

Now create the measures you need.

Total Indoor = 
CALCULATE([Sum Records], 'Game Stats'[Game Type] = "Indoor")

% Indoor = 
VAR _TotalIndoor = CALCULATE([Total Indoor], ALL('Dim Area'), 'Game Stats'[Game Type] = "Indoor")
RETURN
IF(
    MAX('Dim Period'[Order]) = 2, DIVIDE([Total Indoor], _TotalIndoor))

Change =
VAR _Change =
    CALCULATE (
        [Sum Records],
        REMOVEFILTERS ( 'Dim Period'[dFinancial Year] ),
        'Dim Period'[Order] = 1,
        'Game Stats'[Game Type] = "Indoor"
    )
        - CALCULATE (
            [Sum Records],
            REMOVEFILTERS ( 'Dim Period'[dFinancial Year] ),
            'Dim Period'[Order] = 2,
            'Game Stats'[Game Type] = "Indoor"
        )
RETURN
    IF ( MAX ( 'Dim Period'[Order] ) = 1, _Change )

Carrom = 
VAR _Game = CALCULATE([Sum Records], 'Game Stats'[Game] = "Carrom")
RETURN
IF(MAX('Dim Period'[Order]) = 2, _Game)

Chess = 
VAR _Game = CALCULATE([Sum Records], 'Game Stats'[Game] = "Chess")
RETURN
IF(MAX('Dim Period'[Order]) = 2, _Game)

Cricket = 
VAR _Game = CALCULATE([Sum Records], 'Game Stats'[Game] = "Cricket")
RETURN
IF(MAX('Dim Period'[Order]) = 2, _Game)

TT = 
VAR _Game = CALCULATE([Sum Records], 'Game Stats'[Game] = "TT")
RETURN
IF(MAX('Dim Period'[Order]) = 2, _Game)

Now create the Matrix column table using:

Matrix =
VAR _periods =
    VALUES ( 'Game Stats'[Financial Year] )
VAR FP =
    {
        ( "Total Indoor", NAMEOF ( 'Field Parameters'[Total Indoor] ), 0 ),
        ( "% Indoor", NAMEOF ( 'Field Parameters'[% Indoor] ), 1 ),
        ( "Change", NAMEOF ( 'Field Parameters'[Change] ), 2 ),
        ( "Carrom", NAMEOF ( 'Field Parameters'[Carrom] ), 3 ),
        ( "Chess", NAMEOF ( 'Field Parameters'[Chess] ), 4 ),
        ( "Cricket", NAMEOF ( 'Field Parameters'[Cricket] ), 5 ),
        ( "TT", NAMEOF ( 'Field Parameters'[TT] ), 6 )
    }
RETURN
    CALCULATETABLE ( CROSSJOIN ( FP, _periods ) )

Create the relationship between the Dim Period table and the Matrix table:

 Set up the matrix with the Dim Area fields for rows, the dFinancial Year from Dim Period & the Matrix column, and add the measures in order to get this:

 Unfortunately there are blanks fields (the measures themselves set these blanks) for "Columns" which you do not wish to have. To get rid of them, turn off Word Wrap for Column Headers and values:

Now you can hide the rogue columns by draggin the column boundary:

 Since the values are all individual measures, you can now apply the conditional formatting as you wish:
