What is Sketch to Game?
Sketch to Game is one of Gummy’s most magical features. Instead of describing your game in words, you draw it by hand — a rough sketch of a level layout, a character silhouette, or a world map — and Gummy’s AI interprets your drawing and builds a real, playable game from it.How to use Sketch to Game
Open the Create screen
From the home screen, tap Create. On the prompt screen, tap the Sketch icon (pencil icon, top right).
Draw your idea
Use your finger or stylus on the canvas. You can draw:
- Level layouts — platforms, walls, gaps, ramps, and paths
- Characters — rough outlines of your player character or enemies
- Environments — mountains, buildings, terrain features
- Objects — coins, doors, levers, hazards
Add an optional text hint
Below the canvas, add a short text description if you want to guide the interpretation:
"sci-fi dungeon", "underwater", "cartoon style".Tap Generate
Gummy analyzes your sketch and generates a playable game based on what you drew. This takes ~30–45 seconds.
Tips for great sketches
- Keep it simple — clean, clear shapes work better than detailed drawings
- Draw from the side for platformers — Gummy interprets side-view sketches as platformer levels
- Draw from above for top-down games — overhead sketches generate top-down shooters, RPGs, or maze games
- Mark hazards clearly — draw spikes, lava, or gaps distinctly from safe ground
- Use the text hint — even a single word like
"castle"or"jungle"dramatically improves the output

| Character creation | Draw a silhouette and Gummy generates a matching sprite |
| Maze/puzzle games | Hand-drawn mazes become playable puzzle levels |
| Classroom projects | Kids love seeing their drawings come to life |
