Answer

You still need to put the gamebox onside the html at the end of the script:

var gameBox = document.getElementById("i").innerHTML;
for ( var i = 0 ; i < 3 ; i++ ) {


    gameBox += "";
    for ( var j = 0 ; j < 3 ; j++ ) {
        gameBox += "";
    }
    gameBox += "";
        console.log(gameBox);
}
document.getElementById("i").innerHTML = gameBox;
