March Madness is a huge business and it doesn’t take much to find free-to-enter contests that you can sign up and join. Now, the obvious ones are always available, including the March madness challenges being offered by the likes of CBS, ESPN, and Yahoo. But there are other ways to get into the hysteria to the tournament without having to put up some money in the process.  Let’s start with the three sports websites.

Of the three, Yahoo’s the only one that has guaranteed a monetary prize to the best overall bracket. Co-sponsored with Lexus, Yahoo is hosting Tourney Pick’em for two consecutive year. The winner of the Yahoo ”Best Bracket” contest gets $50,000, which will be determined by a completely convoluted and incredibly complicated formula that tacks on different points depending of the correct picks made in any round. I’m not going to begin to try to understand how it works, but for those interested to sign up, you can do so provided you meet their requirements. Only US residents are allowed to play and even then, you’ll have to be 18 in most states and 19 in both Alabama and Nebraska to be allowed.

If you’re not into cash prizes and prefer something a little more in kind, CBS’ annual Free Bracket Challenge. It doesn’t guarantee a prize for a perfect bracket, but it does reward a participant who is among the top ten percent of eligible point scorers with a “with a grand prize” that includes four tickets to the 2017 Final Four and $6,000 to help cover the cost of attending next year’s tournament. The caveat here is that you don’t need to have the best bracket to win. Just get into the aforementioned “top 10%” and, well, pray that your number is called. CBS’ bracket challenge is available to those based in the US but unlike Yahoo and ESPN, it is also open to people from Puerto Rico and Canada (excluding Quebec).

Then we get to ESPN, together with Allstate as well as new sponsors Honda and Microsoft, is dangling a prize package valued at 19,950. The package includes a one trip for two to the 2016 Maui Jim Maui Invitational, airfare and accommodation and a $10,000 Amazon.com Gift Card. Total ARV: $19,950.00. It’s worth noting that the prize winner must be able to travel to Hawaii from November 19-24, 2016. Inability of the winner to travel on those dates will result in forfeiture of the grand prize. It’s a little more difficult field to gain entry to compare to CBS, but you have to admit that the package is a little more alluring than CBS’ offer. Entrants for the ESPN challenge must also be based in the US and must be 18 years and above to join.
