How to Play 20-0: A Full Rules Walkthrough

20-0 has three phases: draft, regular season, and — if you earn it — the playoffs. Here’s exactly what happens at each step.

1. Spin for an era

Every one of the nine draft rounds opens with a spin. The wheel lands on a decade of NFL history, from the 1960s through the 2020s, and hands you a small pool of candidates styled after that era’s football. A 1960s spin leans run-first and physical; a 2020s spin leans pass-heavy and athletic. All players are original, fictional archetypes built for the game — there are no real NFL names, photos, or licensed stats involved, so nothing here is scraped from anyone’s actual career.

You don’t have to draft from the era you spin — the candidates are just flavored by it. What matters is the position.

2. Draft nine, one per position

Nine rounds, nine positions, no skipping:

1. Quarterback
2. Running back
3. Wide receiver (first)
4. Wide receiver (second)
5. Tight end
6. Offensive line
7. Defensive line
8. Linebacker
9. Defensive back

Each round shows up to three candidates. Every card lists an overall rating and a handful of category ratings — passing, rushing, coverage, blocking, and so on depending on position — plus a couple of named strengths and a weakness. Pick one and move to the next round.

Classic mode shows all of that. Blind Draft mode hides the numbers and shows only name, position, and archetype — you’re drafting on vibes and knowledge of what an archetype like “Gunslinger” or “Two-Gap Anchor” usually means, not a spreadsheet.

You get three total rerolls across the whole draft, not per round, so spend them on rounds where the era’s candidate pool genuinely doesn’t fit what you’re building.

3. The regular season sim

Once all nine slots are filled, the game computes your team’s ratings — offense, defense, pass game, run game, trenches (offensive and defensive line play combined), and a chemistry score based on how your specific nine picks interact — and simulates a full regular season game by game.

The schedule length is era-accurate, not a flat number: 14 games for rosters built around the 1960s and 1970s, 16 games for 1978 through 2020, 17 games for 2021 onward. That means a flawless run through a 1960s-flavored roster and a flawless run through a modern one represent different amounts of work before the playoffs even start.

Each game result comes with a short line explaining what happened — a matchup factor tied to your opponent’s tendencies, not just a random score.

4. The playoffs — the part most games in this genre skip

Finish the regular season with a strong enough record and you earn one of seven playoff seeds in your conference. This is where 20-0 does something most competitors don’t: it actually simulates the postseason using the real NFL format, not a coin-flip or a skipped step.

The #1 seed gets a bye through Wild Card weekend. Every seed then plays a genuine single-elimination bracket: Divisional round, Conference Championship, and the Super Bowl for anyone who survives that far. Lose any single game and the run ends there — there’s no best-of-anything to fall back on, exactly like the real thing.

Win every regular-season game and every playoff game and you’ve done it: 20-0.

5. Results, grade, and sharing

The results screen shows your final grade (S through F, where S means a zero-loss regular season), your best pick, your biggest weakness, and — if you made the playoffs — a full breakdown of every postseason game. Every run also generates a short, shareable seed. Send it to a friend and they’ll get the exact same sequence of draft options you did, so you can compare a genuine head-to-head.

If you’re playing the Daily Challenge (everyone gets the same seed that day), you can submit your regular-season record to a public, no-account-required leaderboard.
