I will have up to 10 rounds. How can i do something like

for (i=1; i<10; i++) {
  console.log(this.gameProvider.currentGame.round + i + .character4.somevalue);
}

Use bracket notation.

gameProvider = {currentGame:{}}

for (i=1; i<10; i++) {
  this.gameProvider.currentGame['round' + i ] = {character4: {somevalue: 'asdf'}};
}

for (i=1; i<10; i++) {
  console.log(this.gameProvider.currentGame['round' + i ].character4.somevalue);
}
