One League.Eight Sports.One Champion.

A multi-sport fantasy league is a single fantasy league that tracks multiple professional sports at the same time. Instead of managing a football team in one app, a baseball team in another, and a basketball team in a third, you manage one franchise across all your sports in a single dashboard. Your roster, your standings, your trades, and your championship race all live in one place — 365 days a year.

The flagship format is the four-sport cumulative league: one franchise competing across MLB, NFL, NHL, and NBA. Your final placement in each sport (1st through 12th) earns points on a 14–1 scale, and those points combine into a single year-round championship. Every sport matters. Every season feeds the same title race. You can also create custom multi-sport leagues mixing any 2+ sports — MLB + NFL + NASCAR, NBA + NHL + Soccer, or whatever combination your group wants.

In a traditional fantasy league, you win or lose one sport and start over next year. In a cumulative league, your performance across all sports feeds one championship. Here's the point scale based on your final placement in each sport:

Win the MLB championship and you earn 14 points. Finish last in the NFL and you still get 1. Those points stack across all four sports, so the ultimate champion is the franchise that performs consistently across the entire year — not just the best football manager or the best baseball manager. It rewards versatility, depth, and year-round engagement.

Fantasy365 supports full dynasty keeper leagues with contract tracking and price escalation. At the end of each season, you declare which players to keep. Each kept player has a keeper price that counts against your auction draft budget, and that price escalates each year you keep them — so keeping a star forever costs more and more, forcing strategic decisions about when to let a player return to the pool.

Contract years track how many consecutive seasons a player has been kept. When a player reaches the maximum contract length, they must return to the draft pool — preventing one franchise from hoarding elite talent indefinitely. This creates a natural salary-cap dynamic that keeps leagues competitive year after year, even with the same group of owners.
