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

1

Open the Create screen

From the home screen, tap Create. On the prompt screen, tap the Sketch icon (pencil icon, top right).
2

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
You don’t need to be a great artist. Gummy understands intent, not perfection.
3

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".
4

Tap Generate

Gummy analyzes your sketch and generates a playable game based on what you drew. This takes ~30–45 seconds.
5

Play and refine

Play the result and open the editor to fine-tune. You can use the full visual editor on any sketch-generated game.

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
