Judge & Evaluator
The winner of this SVG challenge is
Gemini 2.5 Pro Preview 05-06
Player 2
Judge's Analysis
Player 2's submission is more vibrant and detailed, with a clear checkerboard track and a visible finish line that enhances the storytelling.
The rocket-powered snail and wind-up turtle are more expressive and dynamic, adhering better to the prompt.
While Player 1's design is clean, it lacks the same level of creativity and visual engagement as Player 2's submission.
These metrics analyze technical aspects of both SVG drawings. Look for differences that might explain the judge's decision. Use the "View Code" button above to see the SVG code for each drawing.
