What Is Stewardle? The F1 Guessing Game Every Formula 1 Fan Should Know

Stewardle is a free, daily Formula 1 driver-guessing game in the style of Wordle — a motorsport trivia puzzle. Each day, a random F1 driver is picked, and players have six attempts to name them using statistical clues — nationality, team, race wins, championships and more — pulled live from the Jolpica API (formerly the Ergast API) (https://github.com/ssyyhhrr/stewardle).

What Is Stewardle? (Wordle for F1 Fans)

Stewardle is a daily guessing game built specifically for Formula 1 fans. Instead of five-letter words, the puzzle each day is a mystery F1 driver, and instead of plain letter feedback, the game helps you narrow the field with real driver statistics.

The game is open-source and lives on GitHub under the user ssyyhhrr, with a playable demo at stewardle.com (https://github.com/ssyyhhrr/stewardle). According to the project's README, it was "created with Express and Node.js" and runs its clues on "live data from the Jolpica API" — the community-run successor to the long-standing Ergast F1 data API (https://github.com/ssyyhhrr/stewardle).

That data-driven approach is what separates Stewardle from a plain word puzzle. You are not guessing blindly at letters; you are using what you know about the sport — who drove for whom, who has championships, who carries which car number — to zero in on the Driver of the Day.

How Stewardle Works

The loop is simple and addictive:

1. A random F1 driver is selected as the day's mystery driver.
2. You type a guess, which must be a valid F1 driver name from a driver who has raced in the 2014 season or later.
3. After each guess, the game gives you feedback through statistical clues rather than plain letters.
4. You have six tries to name the correct driver.
5. A new Stewardle becomes available each day (https://stewardle.com).

The clues are what make the game clever. The official demo explains the feedback with examples: after a guess, tiles and messages tell you things like "The driver is of British nationality," "The driver does not race for Mercedes," or "The driver previously raced for Williams." Number-based clues work the same way — a guess of car number 44 might return "The number is too low," while 103 returns "The number is too high" (https://stewardle.com).

According to the project's description, the full clue set covers nationality, team, race wins, championships "and more" — all retrieved live from the Jolpica API, so the statistics reflect real, up-to-date F1 data rather than a hard-coded list (https://github.com/ssyyhhrr/stewardle).

That matters because it changes the skill being tested. In classic Wordle, your edge comes from letter frequency and vocabulary. In Stewardle, your edge is F1 knowledge: knowing which drivers have championships, who switched teams recently, and which nationalities dominate the grid narrows your guesses far faster than luck alone.

Game Modes

Stewardle is typically played in two modes (https://wordle2.io/stewardle):

• Daily challenge (Today's Challenge). One mystery driver per day, shared by everyone who plays. This is the core experience — the same driver for the whole community, with results you can compare and share with friends.
• Infinite mode. Unlimited practice rounds. Each round picks a random F1 driver, so you can play as many games in a row as you like while you wait for the next daily puzzle.

The daily mode creates the same ritual that made Wordle a phenomenon: one puzzle, one chance to get it right, and a reason to come back tomorrow. Infinite mode is there for practice — and for settling arguments about who knows the 2019 grid better.

How to Play Stewardle: Step by Step

1. Open stewardle.com. The game runs in the browser — no download or installation is required (https://stewardle.com).
2. Read the rules. You get six tries, and every guess must be the name of a real F1 driver who has raced in the 2014 season or later (https://stewardle.com).
3. Make your first guess. Pick any driver who meets the eligibility rule. Your first guess is really a data-gathering move — it reveals the first batch of clues.
4. Read the statistical feedback. Check the nationality, team and number clues. Green-style confirmations tell you a stat matches (for example, "The driver is of British nationality"); negative clues ("The driver does not race for Mercedes") eliminate options; number clues tell you whether to go higher or lower (https://stewardle.com).
5. Narrow the field. Combine what the clues told you: same nationality, a particular team history, a championship count. Each guess should eliminate as many drivers as possible.
6. Solve it within six tries. Name the mystery driver before your attempts run out, then share your result — and come back tomorrow for a new driver.

One practical note: guesses must be valid driver names, not random words. Typing a nonsense entry will not be accepted, so your opener has to be a genuine F1 driver from the 2014 season onwards (https://stewardle.com).

Strategies and Tips for Stewardle

• Lead with stat clues, not letters. Unlike Wordle, Stewardle's richest information comes from nationality, team and championships. A guess that reveals the driver's nationality and team can eliminate most of the grid in one move (https://stewardle.com).
• Start with well-connected drivers. Open with a driver whose career spanned several teams — a long career gives the game more team-history clues to react to, and a wrong guess still tells you a lot.
• Use name length to eliminate candidates. In Wordle-style letter-grid versions of the game, paying attention to the length of the driver's name lets you rule out drivers whose names are too short or too long before you waste a guess (https://wordle2.io/stewardle).
• Play the number clues like a binary search. When a car number comes back "too low" or "too high," split the difference on your next guess, the same way you would in a number-guessing game (https://stewardle.com).
• Lean on championship counts. Very few drivers have multiple championships, so a high championships clue collapses the candidate list almost immediately. If the clue says zero championships, the field is wider — switch to team and nationality clues instead.
• Think in eras. The eligible driver pool starts with the 2014 season, so recent-grid knowledge goes furthest. If the clues point to a team that only existed in the mid-2010s, you are probably looking at a driver from that era (https://stewardle.com).
• Use infinite mode to learn the grid. Treat infinite mode as a training ground: the more drivers you guess, the faster you internalise who drove where and when — and that knowledge transfers directly to the daily challenge (https://wordle2.io/stewardle).

Stewardle vs Other Sports Guessing Games

Stewardle is part of a growing family of Wordle-inspired sports guessing games — daily motorsport trivia with a data edge. Here is how it compares:

Stewardle's distinguishing feature is its live API data. Because the clues are retrieved from the Jolpica API rather than a static list, the statistics behind each puzzle stay current with real F1 records (https://github.com/ssyyhhrr/stewardle). It is also fully open-source, so anyone can inspect, fork or self-host the game — the project even ships a Docker image for that purpose (https://github.com/ssyyhhrr/stewardle).

If you enjoy the daily-guess format, the football equivalent "Who Are Ya?" scratches the same itch for soccer fans. But for F1 fans specifically, Stewardle is the natural daily ritual: one driver, six guesses, and a stats lesson every morning. If you prefer words to wheels, our word puzzle strategies guide sharpens the deduction skills that transfer — and our daily puzzle games collection has more formats to try.
