This is a pet peeve of mine. Consider the Roku interface, especially for Amazon video, where your current selection has a slim yellow border which is hard to see at a glance, and it's slow and unreliable enough that you can get stuck "between frames" wondering if the system is just hesitating or if your button press didn't register. Please, always make selections clear!
I recommend that you highlight the selection with bolding and a border change. Using color alone is usually a bad idea, as it may be open to interpretation and it obviously doesn't work well for people who are colorblind, so start with a grayscale image. You can then add a check mark or a star for correct entries and an X for incorrect, and mark the losers of games that have been played with a strike-through.
Now that you've made all three axes (selection, victory, and correctness) clear, you can reinforce this with color, and no one will depend on it:
I'm not happy with how ties are shown here (neither side crossed out). If the actual UX problem you're trying to solve has three or more common possibilities, I would probably recommend a set of arrows: one pointing from the top to show what you picked, and one from the bottom to show what happened. Success is when the arrows align:
This takes up a lot more vertical space, though.
