Problem with odds and even simulation code

Hello. I'm trying to simulate an even and odds game that scores 100 games. The problem is that when I get the results Player B seems to always win. Can anybody see whats wrong?

ScoreA=0;
ScoreB=0;
for z= 2:100
    PlayerA= randi(2,[100,1]);
    PlayerB= randi(2,[100,1]);
    n= PlayerA+PlayerB;
    if n==3
        ScoreA(z)=ScoreA(z-1)+1;
        ScoreB(z)=ScoreB(z-1);
    else
        ScoreB(z)=ScoreB(z-1)+1;
        ScoreA(z)=ScoreA(z-1);
    end
end

I did not understand very well what you are looking forward. However, I just note your if statement is weird.

For example, for PlayerA = [2 2 1 1 1] and PlayerB = [2 1 1 2 1]; We have ScoreA = [0 0 0 0 0] and ScoreB = [0 1 2 3 4];

In your code, the variable n becomes always 100x1 array. This is the reason why the ScoreB always much higher than ScoreA.

To do your task, how about the following?

PlayerA = randi(2,[100,1]);
PlayerB = randi(2,[100,1]);

PlayerA_Win = mod(PlayerA+PlayerB,2) == 1; % Odd
PlayerB_Win = mod(PlayerA+PlayerB,2) == 0; % Even

ScoreA = sum(PlayerA_Win);
ScoreB = sum(PlayerB_Win);
