Okay I updated the rules because I'm already seeing "or" situations happening. It would be less confusing if they didn't happen but please let me know if you think another way to address "or" situations would be better:
If you choose to make an "or" prediction, such as "smash 7 or Mario Odyssey 5", then if one of them happens you will receive 5 points. If both happen you receive 10 points. If you want to make the full 20 points possible from them, then you must break the "or".
