How it works
Spin for an era
Each round spins a decade of NFL history — 1960s through the 2020s — and hands you a small pool of original, fictional candidates from it.
Draft nine, one per position
QB, RB, two WRs, TE, OL, DL, LB, and DB — nine rounds, offense and defense both accounted for, no flat "best player available" shortcuts.
Survive 16 straight games
Your roster plays out the full 16-game regular season game by game. Win all sixteen and you finish 16-0 — the perfect regular season. Drop one and the streak is over.
What "16-0" actually means
16-0 is a free NFL roster-building game: spin for an era, draft nine players by position across nine rounds, and simulate the classic 16-game regular season to see how far your roster gets. The goal is simple and specific — go 16-0, a perfect regular season under the schedule the NFL used from 1978 through 2020. That is the exact format the 2007 New England Patriots became the only team ever to run the table in.
No playoff bracket, no era-scaled schedule tricks — just sixteen games, and whether your roster can win every single one. It is the regular-season-only sibling of our companion game at 20-0.online, which adds a full playoff run for the players who want the whole gauntlet. Here, the dare is the purest version: sixteen wins, zero losses.
Why a perfect regular season is so rare
In the 43 seasons the NFL played a 16-game schedule (1978–2020), exactly one team finished it without a loss. Winning any single NFL game is close to a coin flip even for a great team; winning sixteen in a row against a real schedule is a different order of difficulty entirely. See our breakdown of why 16-0 almost never happens for the real math.
16-0 vs 17-0 vs 19-0 vs 20-0
The numbers get confusing fast. 16-0 is a perfect 16-game regular season. A modern regular season is 17 games, so a perfect one today would read 17-0. The 1972 Dolphins' fully perfect season was 17-0 counting playoffs. And a perfect modern season with playoffs would be 20-0. Our full explainer sorts out every version of the perfect-season math.

What is 16-0?
A free browser game: spin for an era, draft nine players — one per position, quarterback through defensive back — then simulate the classic 16-game NFL regular season. "16-0" is the target: a perfect regular season with zero losses. It is the exact record the 2007 New England Patriots became the only team to reach under the 16-game schedule. There is no playoff bracket in this game; you win by finishing 16-0.
Why 16 games and not 17?
The NFL played a 16-game regular season from 1978 through 2020 — the format for the entire modern era of famous perfect-season runs, including the 2007 Patriots. This game is fixed to that classic 16-game slate so every era is judged on the same, historically iconic length. The league expanded to 17 regular-season games in 2021.
Is 16-0 free to play?
Yes, entirely free, with no account required to play, save progress, or submit to the leaderboard.
How many players do you draft?
Nine picks total, one per position: quarterback, running back, two wide receivers, tight end, offensive line, defensive line, linebacker, and defensive back. Every round is locked to a real position on offense or defense.
Has any real NFL team ever gone 16-0?
Yes — exactly one. The 2007 New England Patriots went 16-0 in the regular season, the only team to complete a perfect 16-game regular season. They then won their first two playoff games to reach 18-0 before losing Super Bowl XLII to the New York Giants, finishing 18-1. Under the earlier 14-game schedule, the 1972 Miami Dolphins went 14-0 in the regular season on the way to the only fully perfect season (17-0 including playoffs).
What is the difference between 16-0 and 20-0?
16-0 is a perfect regular season under the classic 16-game schedule. 20-0 would be a perfect season under the modern 17-game schedule with all three playoff wins added (17 + 3). This game is the regular-season-only challenge; our companion game at 20-0.online adds a full playoff bracket on top.
Does the game simulate the playoffs?
No. 16-0 is deliberately a regular-season-only game — the pure "perfect regular season" challenge. Your run ends when the 16-game schedule does, and finishing 16-0 is a win. If you want the playoffs-included version, play our sibling game at 20-0.online.
Is there a Daily Challenge and leaderboard?
Yes. Everyone who plays on the same day gets the exact same sequence of draft options, and you can submit your 16-game record to a live, public leaderboard — no account required.
Can I replay a friend's exact draft?
Yes. Every run generates a shareable seed. Enter someone else's seed on the welcome screen and you get the exact same sequence of draft options they had — make the same picks for a mirror match, or different picks for a real head-to-head comparison.
