Frequently asked questions

Everything you might want to know about Perfect XI — how it works, the modes, the data, and the chase for a perfect season. Still stuck? Email us.

Is Perfect XI free to play?

Yes. Perfect XI is completely free and runs in your browser. There is nothing to buy to play the full game. Optional tips are welcome but never required.

Do I need to download anything or sign up?

No. There's no app to install and no account to create. Open the page and start playing straight away. Your saved runs are kept locally on your device.

What is a 38-0 season?

It's a perfect Premier League campaign: 38 games played, 38 won, with no draws and no defeats. It's the hardest goal in the game and the thing most players are chasing.

Has any real team ever gone 38-0?

No. Arsenal's 2003-04 "Invincibles" went unbeaten but drew twelve games, and Manchester City's 2017-18 side hit 100 points yet still lost twice. A flawless 38-0 has never happened in real life — but it's achievable in the game.

How is my team's rating calculated?

Your overall rating comes from the ratings of all eleven players, weighted by how well each fits the position you placed them in, plus a bonus for a balanced side. One weak link lowers your ceiling, so spread your quality across the team.

What data and ratings does the game use?

Real clubs and squads across many seasons, with player and team ratings that are a fan interpretation built for gameplay and derived from a public football dataset. The ratings are not official and aren't endorsed by any club, league or data provider.

What is Expert mode?

In Expert mode the ratings are hidden while you draft — you see only names and positions and pick on football knowledge alone. The numbers and your final record are revealed at the end. Normal mode shows ratings as you build.

What is World Cup mode?

A tournament twist: build a World XI by drafting one player from each nation you roll, or lead a single country through the competition, then simulate your run to the final.

What is Versus mode?

Draft two teams and play them head-to-head in a single match. You can share a code so a friend can take on your exact line-up.

Can I really go unbeaten?

Yes, but it's deliberately rare. You'll need top-rated players in every position and a bit of luck. Most teams land somewhere between a relegation scrap and a title challenge — read the 38-0 guide for the best approach.

Does it work on mobile?

Yes. Perfect XI is designed to play well on phones, tablets and desktops in the browser.

Is Perfect XI affiliated with the Premier League?

No. It's an independent, unofficial fan game. It isn't affiliated with or endorsed by the Premier League, FIFA, any club, or any ratings provider. Club and player names belong to their respective owners.

How do I share my team or result?

Finish a run and you can share your line-up and record. In Versus mode a shareable code lets a friend replay your exact match-up.

How do I report a bug or suggest a club?

Email perfectxigame@gmail.com or message @perfectxigame on X. Feedback on missing clubs, seasons or players is always welcome.

What is Dynasty mode?

Dynasty is the multi-season career: your XI carries over with ages, players develop and retire, league finishes earn transfer budgets, and a board sets targets your manager rating depends on. The full rules — age curves, budget table, values, the sack — are in the complete Dynasty guide.

How do player ages work in Dynasty?

Each player is assigned a career age (22–32) when the dynasty starts. Under-24s grow each summer, 28+ begins the decline, and at 33–34 players retire. Ages are assigned for gameplay — the base game outside Dynasty doesn’t use them.

What is squad chemistry and is it worth chasing?

Players who share a club or a season link, and links convert to up to +3 effective OVR in every match — usually the biggest free upgrade available. The formula and a worked example are in the chemistry guide.

How does the Daily Challenge work?

Everyone gets the same seeded spin sequence each day, one attempt. Finishing locks your result and creates a shareable scorecard with a match-by-match grid. It resets at midnight; details in the modes guide.

How do friend duels work?

Start a duel to play a seeded run, then copy the code from your results — it carries the spin seed and your score. Anyone entering it drafts from your exact spins, and their results screen declares the winner with a rematch code back. No accounts needed.

Will I lose my run if I close the tab?

No — the game autosaves at every safe point (each pick, each match). Reopen the site and a “Continue your run” card appears on the home screen. Saves live in your browser’s local storage and expire after seven days.

Can I play offline or install it as an app?

Yes. After your first visit the game caches itself for offline play, and on Android/desktop Chrome you can use “Install app” for a full-screen, home-screen version. On iPhone, use Share → Add to Home Screen.

What are the weekly events?

A rotating rule-twist each week — Nineties, Y2K, Moneyball (no one above 85), Modern Era, and Homegrown (British & Irish only). The rotation and strategy notes are in the modes guide.

What is Blitz mode?

A faster ruleset: each spin offers only the top three picks and the season simulates instantly once your XI is complete — a full run in about three minutes. Toggle it on the setup screen.

Where do the player ratings come from?

They’re a fan interpretation built for gameplay from a public football dataset, hand-balanced across eras and clubs — not official statistics. How the 2,866-player database was built, and its exact top ten, is covered here.
