Is the 17-0 NFL game free to play?

Yes. It runs free in any browser with no download and no sign-up required — an account is only needed for leaderboards and prizes.

How does the 17-0 game work?

Draft an all-time NFL roster from random team and era draws, then simulate the season and chase a perfect 17-0 run. Every loss ends the perfect season, and finished runs are scored on global leaderboards.

What is the best strategy?

Spend your skips early rather than hoarding them, keep roster slots flexible so a late superstar always has a home, and mind era adjustments — a dominant modern season usually beats bigger raw numbers from early eras.

🔄 One franchise re-draw + one era re-draw for the whole roster
🏈 Build an identity: your QB drives the Offense; the front seven and secondary are all of your Defense.

About the 17-0 NFL challenge

84-0's NFL mode is a free browser game where you draft an all-time NFL roster one random draw at a time. Draft an all-time NFL roster from random team and era draws, then simulate the season and chase a perfect 17-0 run.

Each draw offers players from a random team and era, and you keep exactly one — build the strongest possible lineup, then watch the simulation play out. One loss ends the run, so a true 17-0 season is genuinely rare.
