The 2025 NCAA Men’s Basketball Tournament, or March Madness, is underway with the 64-team playoff. Along with March Madness come myriad contests, as bracket-mania sweeps the nation.

Which March Madness bracket contests should you enter in order to win big prizes? We at TheLines will circle the best free bracket contests once they are announced for the 2025 Big Dance.
TheLines’ March Madness Contest

Traditional DK Bracket Challenge
DraftKings had several free bracket challenge contests to play in 2025. One of the top options is the DraftKings Jimmy John’s & All the Smoke Bracket Challenge. Users who reserved a spot need to come back to fill out bracket before the first game tips.
The DraftKings free bracket challenge is a pretty standard bracket picking contest. The scoring doubles for each round as follows:
- First Round: 10 points
- Second Round: 20 points
- Sweet 16: 40 points
- Elite 8: 80 points
- Final Four: 160 points
- National Championship: 320 points
Contestants can only make one entry. Be aware that individuals in jurisdictions that bar betting on in-state college teams won’t be able to pick such teams in the game.
DraftKings has flattened out this year’s payouts to the following format:
- 1st: $5,000
- 2nd-3rd: $1,000
- 4th-5th: $500
- 6th-15th: $100
- 16th-115th: $50
- 116th-755th: $25
- 756th-1755th: $10
- 1756th-2755th: $5
Even those who finish 2756th – 7755th will receive something: a crisp George Washington in their account.
