If the number of games is fixed, you can do very simply:

var scores = {
  game1: 55,
  game2: 62,
}
scores.average = (scores.game1 + scores.game2) / 2;
console.log(scores);

If the number of games isn't fixed, you can loop through the properties of the object and add each value to an array, then calculate the sum of the array and divide by its length to get the average.

var scores = { game1 : 55, game2 : 62}
var scoreArr = [];
for(const a in scores){
  scoreArr.push(scores[a]);
}
scores.average = scoreArr.reduce((a, b) => a + b, 0) / scoreArr.length;
console.log(scores);
