What is 16-0?
16-0 is a fast, free NFL roster-building game: spin for an era, draft one player per position across nine rounds — quarterback through defensive back — simulate a full 16-game regular season, and see if your roster can finish it undefeated. A perfect run is 16-0, and the goal ends there: the whole game is the regular season. It's built in the same spirit as the small genre of viral "draft an all-time roster and chase an undefeated season" games, but it's an original, independently built game, not a clone of any of them, and not affiliated with any of them.
Why 16-0? The 2007 Patriots milestone
16-0 is the most famous perfect regular-season record in the modern NFL: the 2007 New England Patriots are the only team to finish a full 16-game regular season without a loss. 16-0 the game chases that same milestone — a flawless 16-game season — with a roster you build yourself. It deliberately stops at the regular season, the same place that 16-0 record lives: the 2007 Patriots went undefeated through the regular season and then lost in the postseason, so in this game the perfect 16-game run is the win.
How to play
Each of the nine rounds targets a specific position: quarterback, running back, two wide receiver slots, tight end, offensive line, defensive line, linebacker, and defensive back, in that order. Spin to reveal an era and a candidate pool, pick your player, and move to the next round. A limited number of rerolls are available if a spin leaves you with nothing that fits. Once all nine positions are filled, the 16-game regular season simulates automatically and the run is scored — no bracket, no bye, no Super Bowl.
16-0 vs. 17-0 vs. 20-0: what's the difference?
16-0, 17-0, and 20-0 share the same draft and NFL simulation engine but stop in different places. 16-0 pins every run to the classic 16-game season, so the target is always a fixed 16-0 — the record the 2007 Patriots posted. 17-0 uses an era-accurate schedule, which can be 14, 16, or 17 games depending on which eras your roster represents. 20-0 keeps going past the regular season: an undefeated season earns the #1 seed and a bye, then three single-elimination playoff wins turn a perfect regular season into a full 20-0. Pick 16-0 for the pure classic-season chase, 17-0 for the era-accurate version, or 20-0 when you want the playoff gauntlet on top.
Why every pick has to fill a real position — offense and defense
Most games in this genre score a roster by totaling raw production with no real check on roster balance. 16-0 locks each of its nine rounds to a specific position, on both sides of the ball — a roster with no real pass rush or no coverage help behind it gets caught by the chemistry system, not just discovered the hard way when the season simulates.
Classic vs. Blind Draft
Classic mode shows full ratings while you draft, so you can make informed, strategic picks. Blind Draft hides every number — you're drafting on position, archetype, and what you actually remember, then finding out how good your instincts were when the season simulates.
Daily Challenge and leaderboard
Every player who loads 16-0 on the same day gets the exact same sequence of draft options. Submit your result to the live leaderboard — no account required to play or to submit. 16-0 keeps its own separate board and its own saved bests, so your runs never mix with 17-0's or 20-0's.
Frequently asked questions
Is this 16-0 affiliated with the NFL or any other game?
No. This is an independent, original game. It is not affiliated with, endorsed by, or licensed by the NFL, and it is not a clone of or affiliated with any other roster-building game. It is also not the same as our 17-0 game — 16-0 pins every run to the classic 16-game regular season instead.
What is the goal in 16-0?
Finish the classic 16-game NFL regular season undefeated. Every run is a 16-game schedule no matter which eras you draft from, so a flawless finish is always 16-0. There is no playoff bracket — the perfect regular season is the whole game.
Why 16-0? Is this the 2007 Patriots?
The 16-0 record is famous because of the 2007 New England Patriots, the only team to go 16-0 across a full 16-game regular season. This game is not about that team — it is a build-your-own-roster challenge — but it chases that same milestone: a perfect 16-game regular season. (The 2007 Patriots then lost in the playoffs, which is exactly why 16-0 stops at the regular season.)
How is 16-0 different from 17-0 and 20-0?
All three share the same draft and NFL simulation engine. 16-0 pins the schedule to the classic 16-game season (1978–2020 length) for a fixed 16-0 target. 17-0 uses an era-accurate schedule — 14, 16, or 17 games depending on the eras you draft. 20-0 keeps going past the regular season into a three-round playoff bracket. Each runs on its own separate leaderboard, so results never mix.
Is 16-0 free to play?
Yes, entirely free, with no account required. Progress and personal bests are saved to your browser only.
How many players do you draft?
Nine, one per round: quarterback, running back, two wide receivers, tight end, offensive line, defensive line, linebacker, and defensive back — a real position on both sides of the ball, not just skill picks.
What is the difference between Classic and Blind Draft mode?
Classic shows full player ratings while you draft. Blind Draft hides every number — you draft on position, archetype, and what you actually remember, then see how your instincts held up once the season simulates.
Is there a Daily Challenge and leaderboard?
Yes — everyone who plays 16-0 on the same day gets the exact same sequence of draft options, and you can submit your result to a live leaderboard. It runs on its own separate board, so a 16-0 run never mixes with 17-0 or 20-0 results.
When does the Daily Challenge reset?
At midnight UTC. The seed is generated from the current UTC date, so a fresh challenge — and a fresh leaderboard — starts the moment the date rolls over on the server, regardless of your local time zone.
Can I replay a past Daily Challenge or see an archive of old days?
Not right now — there is no archive or day-picker, and Daily Challenge always loads today's UTC seed. You can still revisit a specific draft any time by typing its seed code into the seed field on the welcome screen; that reproduces the exact same draft options, just not attached to that day's leaderboard.
How exactly is chemistry scored?
Chemistry starts at a baseline of 60 and moves up or down from named, concrete triggers checked against your actual roster: an accurate QB plus two real receiving threats earns Elite Passing Attack (+8), a strong offensive and defensive line together earns Dominant Trenches (+7), and a mobile QB paired with a workhorse RB earns Explosive Backfield (+6). Penalties work the same way — a weak line protecting a high-usage QB triggers Leaky Protection (-7), and a linebacker and defensive back who both grade low in coverage trigger Exposed Secondary (-7). Every effect is shown by name in your results so you can see exactly what helped or hurt.
Can I share or download my result?
You can share it as text — tapping Share opens your device's native share sheet (or copies the result and seed to your clipboard if Web Share isn't supported) with your record, grade, and seed so a friend can load the same draft. There is no image/graphic export yet.
Can I play head-to-head against a friend?
There is no built-in challenge-a-friend mode, but you can get the same effect two ways: send them your seed code so you both draft from the identical candidate pool and compare records, or both play the same day's Daily Challenge and check the shared leaderboard.
Is there a salary-cap or budget mode?
Yes — an optional Salary-Cap mode toggle sits on the welcome screen before you start drafting. Turn it on and every player costs a salary based on their overall rating, so you have to build all nine roster spots under a fixed cap instead of just taking the best card available every round. Leave it off for the Classic draft, where every pick costs the same. Either way, roster balance is also enforced by the nine fixed position rounds (one real slot per side of the ball) and the chemistry system, which rewards well-rounded rosters and penalizes lopsided ones.
How many players, eras, and years are in the pool?
76 original player cards spread across all nine draft positions, drawn from six eras — the 1960s through the 2020s — with individual season years ranging from 1962 to 2024. Every player is a fictional archetype built for the game, not a real NFL player, so there is no licensing overlap with the league or its players.
Can a season end in a tie, or is there overtime?
No ties. If a simulated game lands on the exact same score for both sides, the engine breaks it with a coin flip that adds a field goal to one team, so every one of the 16 games resolves to a clean win or loss. There is no separate overtime period modeled.
Is my best score saved across sessions and devices?
Your personal best, completed-run history, and flawless count are saved to your browser's local storage, so they persist between visits on the same browser and device without needing an account. They are not synced to the cloud, so a different browser or device starts with a clean slate — only the shared Daily Challenge leaderboard is common to everyone.
Can I undo a pick or redraft after choosing?
No — once you click a player, that pick is locked in and the draft moves to the next round; there is no undo. Before you lock a pick, you get up to three rerolls per run to spin a fresh set of candidates for the round you are currently on if nothing fits.
What if I don't fill every position?
You cannot finish a run without filling all nine — the draft is nine fixed rounds (QB, RB, two WRs, TE, OL, DL, LB, DB) and the season will not simulate until every slot has a player. There is no way to skip a position or draft with a short roster.
Is the final score just win-loss, or is there a margin/rating?
Your headline result is the win-loss record plus a letter grade: S for a flawless 16-0, then A/B/C/D/F based on win percentage for anything short of perfect. Individual game scores exist in the simulation, but the grade and leaderboard are driven by record, not by total point differential.
What is the best draft order or strongest combos?
Build around the named chemistry bonuses rather than just top overall ratings: a high-passing QB with two strong receiving threats and a good tight end (Elite Passing Attack), a mobile QB next to a true workhorse RB (Explosive Backfield), and a linebacker plus defensive back who both grade well in coverage (Shutdown Secondary) are the most reliable stacks. Matching most of your roster to one era also triggers the Era Specialists bonus, while mixing eras too loosely risks the Poor Era Fit penalty.
Is there a hint system?
No dedicated hint system. Classic mode shows full ratings while you draft, which functions as the built-in guidance; Blind Draft deliberately hides every number and only labels stats as hidden, with no hints available, so you are drafting on position and memory alone.
Who made 16-0, and is it maintained?
SportsMonkie built and maintains 16-0 as an independent, unofficial project — it is not affiliated with, endorsed by, or licensed by the NFL. It shares its draft and simulation engine with sibling games <a href="/games/17-0/">17-0</a> and <a href="/games/20-0/">20-0</a>, which are actively developed alongside it.
Has any real NFL team actually gone undefeated?
Yes. The <a href="/1972-dolphins-perfect-season/">1972 Miami Dolphins</a> are the only team to finish an entire season — regular season and playoffs — without a loss, going 17-0 on the old 14-game schedule. The 2007 Patriots are the only team to finish the regular season 16-0 before losing in the playoffs, which is the specific record this game chases. See <a href="/every-undefeated-nfl-team/">every undefeated NFL team</a> for the full list.
