The Super Bowl is the biggest sports gambling day of the year, because you can bet on just about anything. If you want to keep it simple: The Rams are four-point favorites over the Bengals, so that's a bet you can make that everyone understands, but let's get weird. Let's bet on the coin toss. Sure, it's a literal coin flip and none of us have any insight into the result, but stop trying to be reasonable and put some money down already.
You can also wager on the length of the national anthem or the color of Gatorade poured over the winning coach during the postgame celebration.
