  This paper presents the first ChatGPT4PCG Competition at the 2023 IEEE
Conference on Games. The objective of this competition is for participants to
create effective prompts for ChatGPT--enabling it to generate Science Birds
levels with high stability and character-like qualities--fully using their
creativity as well as prompt engineering skills. ChatGPT is a conversational
agent developed by OpenAI. Science Birds is selected as the competition
platform because designing an Angry Birds-like level is not a trivial task due
to the in-game gravity; the quality of the levels is determined by their
stability. To lower the entry barrier to the competition, we limit the task to
the generation of capitalized English alphabetical characters. We also allow
only a single prompt to be used for generating all the characters. Here, the
quality of the generated levels is determined by their stability and similarity
to the given characters. A sample prompt is provided to participants for their
reference. An experiment is conducted to determine the effectiveness of several
modified versions of this sample prompt on level stability and similarity by
testing them on several characters. To the best of our knowledge, we believe
that ChatGPT4PCG is the first competition of its kind and hope to inspire
enthusiasm for prompt engineering in procedural content generation.
