That might also be correct for written as well.
Right. When I was first asked the question, I said that I used the two forms interchangeably. But after I thought about it a little bit, I realized that there is probably a bit of a difference in how I use them, but it was very hard to pinpoint exactly what that difference might be. In your example, there is an implicit comparison because the other option is to not go to the game. I considered that I might be more likely to use the "if" formation in contexts where I'm expecting (or received in the past) an affirmative response, because in that context the alternative is of diminished relevance. And perhaps I'm more likely to say "whether" in contexts where I'm unsure about the response I will receive. In other words, the difference between "I asked if we should go to the game" and "I asked whether (or not) we should go to the game" might depend on whether I'm asking as a formality or if I'm genuinely unsure about the response I will get. I'm not sure if this is how I actually speak or if this is something I just made up which sounds nice. All that said, I think I usually say "if".
Apparently using "if" to mean "whether" is considered incorrect by some people because there are circumstances where it can create ambiguity. I hadn't been aware of that. Or given it any thought, for that matter.
