How do i highlight a particular cell/change color when a particular condition is met.

Okay, let do it bit another way and step by step. I based on my test sheet:

in row 12:12 we have lowest score for all players, and in 13:13 number of such players.

Apply to the cell $B$1 conditional formatting rule

=(B1=B$12)*(B$13=1)

which check if simultaneously B1 has minimum score and we have only one such player in B:B column. Be careful with absolute and relative references in formula, that's important.

After that pick-up format of the cell B1 by Format Painter and apply it sequently to cells B3, B5, B7, B9.

You may stay on cell B9 and check Conditional formatting for it, it shall show the rule

=(B9=B$12)*(B$13=1)

After that select entire column B:B (or only cells B1:B9), pickup its format by Format Painter and apply it to next columns C:C, etc.

For cell C9, for example, it shall appears the rule

=(C9=C$12)*(C$13=1)

 Now you have lot of rules for you matrix, one separate rule for each cell with the score. In my previous post that was one rule applied to set of cells. Result is the same.

If your matrix is as small as in your example and numeber of players is more or less fixed above is enough, for big matrix and flexible number of players some optimization could be applied.
