How to remove blank cells as values in a ladder

I am making a ladder for a PE class tournament, and the wins and losses columns are done with a =if(B5<C5,1,0) to give points or not based on which value is larger, but the draws are giving me strife.

My current formula is =IF(B5=C5,1)+IF(B11=C11,1)+IF(F11=G11,1)+IF(F17=G17,1)+IF(B23=C23,1)+IF(B29=C29,1) to represent all the games the students will play, and if the soccer match ends in a draw, it adds 1 to the draw column. But when all of the cells are blank, the cell tracking draws has a 6 in it because the blank spaces are the same value. Is there a way to change my formula to exclude cell if the cells are blank?
