Claude skillTurn a car you drew on paper into a racing game you can play
A free Claude skill. Draw a car, snap a photo, and Claude turns it into a street race where the car you drive is your car, stripes and wing included. Plus the Higgsfield setup and the exact prompt from my video.

The prompt from my video
No skill? This is the exact prompt from the video. Paste it under your photo and Claude writes a game from scratch. Every run comes out different.
Turn the car in this drawing into a playable desktop racing game using Higgsfield. Keep its recognizable shape, racing stripes and rear spoiler. Use arrow-key controls and a third-person chase camera. Set a two-lap street race through a city against three rivals, with traffic to dodge and nitrous on Shift.
Set it up once
Takes about two minutes. You only do it once.
- Open Claude in your browser and sign in.
- Pick Fable 5.2 in the model menu next to the chat box.
- Open the Higgsfield setup page, make sure the Claude tab is selected, and click Connect to Claude.
- Claude opens its custom connector window. Add the connector. If the address box is empty, paste
https://mcp.higgsfield.ai/mcp. - Sign in to Higgsfield when it asks. That's the whole connection.
- In a new chat, check Higgsfield is switched on in the chat's connectors menu.
Higgsfield is free unlimited for 3 days. My Higgsfield setup link is the link for that offer.
What the skill does
| Step | What happens |
|---|---|
| Read the sketch | Claude reads your drawing: body, colours, stripes and where they run, spoiler, wheels, exhausts, plate |
| Check it | You see it as a short list and fix anything it got wrong |
| Studio photo (optional) | With Higgsfield connected, one clean photo of your car on a dark background, only after you say yes |
| Build | It writes one file, my-race.html |
| Race | Double-click the file, press Enter |
| Tweak | Night, rain, more traffic, monster truck, police chase, more rivals, a new city |
Draw a car Claude can read
You don't need to be good at drawing. You need a car that's easy to recognize.
- Clear silhouette. One dark, closed outline. If you can tell what it is from the shape alone, so can Claude.
- Stripes. Two racing stripes down the hood and roof are the easiest detail to carry into the game.
- A big spoiler. Make the rear wing bigger than feels right. Small details get lost.
- Side or 3/4 view. Straight from the front or top hides the shape. Side or 3/4 shows the wheels, the roofline and the wing.
- One car per page. No scribbles, arrows or notes around it.
- A flat, well lit photo. Paper flat on the table, phone straight above it, daylight or a lamp, no shadow of your hand across it.
Mine was a silver coupe with two blue stripes, a big black rear wing and four exhausts.
What the game is like
A city street race: two laps against three rivals, traffic in three lanes, a countdown, a speedometer and a finish screen with the standings. It's one file that works offline. Open it in Chrome and press Enter.
| Key | What it does |
|---|---|
| Up / Down | Gas / brake |
| Left / Right | Steer |
| Shift | Nitrous (the blue bar refills) |
| R | Back on the road |
| P | Pause |
| Enter | Start, or race again |
Change the game after
Keep going in the same chat. Say it in plain words and the skill rebuilds the game as a new file, so the version that worked is kept.
A wet night chase
Make it night, add rain and a police chase, and turn the traffic up to high.
A monster truck
Turn my car into a monster truck. Keep my colours and stripes.
Harder and longer
Give me five rivals, three laps and a different city.
Draw something else, get a different game
The skill builds car races. For other games, use these prompts the same way as the one from my video. I haven't run them myself, so expect to tweak the result.
A plane becomes a flight game
Turn the plane in this drawing into a playable desktop flight game using Higgsfield. Keep its recognizable shape, wing markings and tail. Use arrow-key controls and a third-person chase camera. Set a course of rings to fly through in a mountain valley, against the clock, with a speed boost on Shift.
A kart becomes a kart racer
Turn the kart in this drawing into a playable desktop kart racing game using Higgsfield. Keep its recognizable shape, colors and number. Use arrow-key controls and a third-person chase camera. Set a three-lap race on a twisty track against five rivals, with boost pads on the road and a drift on Space.
A motorbike becomes a highway race
Turn the motorbike in this drawing into a playable desktop racing game using Higgsfield. Keep its recognizable shape, paint and exhausts. Use arrow-key controls and a third-person chase camera. Set a race down a desert highway against three rival riders, with trucks to weave through and nitrous on Shift.
Off the road: a boat and a spaceship
Same pattern, same caveat: untested prompts to try.
A boat becomes a river race
Turn the boat in this drawing into a playable desktop boat racing game using Higgsfield. Keep its hull shape, stripes and number. Use arrow-key controls and a third-person chase camera. Set a race through a river canyon against three rivals, with rocks and buoys to dodge, waves that throw the boat around and nitrous on Shift.
A spaceship becomes a space race
Turn the spaceship in this drawing into a playable desktop space racing game using Higgsfield. Keep its silhouette, wings and engine glow. Use arrow-key controls and a third-person chase camera. Set a race through an asteroid field against three rival ships, with checkpoint gates to fly through and a boost on Shift.
If something goes wrong
| Problem | Fix |
|---|---|
| The game won't open or shows a blank page | Download the file and open it in Google Chrome on a computer, then press Enter. |
| The car doesn't look like my drawing | Fix the list Claude shows you before it builds: "The stripes are red, not blue, and the spoiler is big." A clearer photo helps too. |
| Claude doesn't use the skill | Start a new chat and say "Use the sketch-to-race skill" at the start of your message. |
| Claude doesn't use Higgsfield | Check the connector is switched on in that chat and that you signed in to Higgsfield. |
| I can't find Fable 5.2 | Open claude.ai in your browser and check the model menu next to the chat box. |
| The car is stuck off the road | Press R. |
The fine print
This is a paid partnership with Higgsfield. The setup link is my Higgsfield link.
The skill is free. MIT licence, no signup. The game needs no API key.
The game in my video is Higgsfield's demo. The skill builds its own arcade-style race around your car. It's a lookalike of your drawing, not a 3D model of it.
Keyboard only. No sound, no online play and no phone controls.
The remix prompts are untested. They're written the same way as my prompt, but I haven't run them. Treat them as a starting point.
The free offer is Higgsfield's. It's free unlimited for 3 days. Check Higgsfield's pricing page for what applies after that.
Use your own drawings. Keep other brands' logos and characters out of your sketch.
