# The Riddle of Togelby

## TL;DR

This paper explores methods to enrich search spaces in game design to increase the likelihood of discovering interesting game elements, focusing on representation techniques and search space modifications.

## Contribution

It introduces approaches for creating and modifying representations to focus search on rich, interesting game components, enhancing game generation processes.

## Key findings

- Rich spaces can be naturally constructed for game elements
- A simple technique can modify representations to focus on interesting parts
- Highly expressive representations restrict search to promising areas

## Abstract

At the 2017 Artificial and Computational Intelligence in Games meeting at Dagstuhl, Julian Togelius asked how to make spaces where every way of filling in the details yielded a good game. This study examines the possibility of enriching search spaces so that they contain very high rates of interesting objects, specifically game elements. While we do not answer the full challenge of finding good games throughout the space, this study highlights a number of potential avenues. These include naturally rich spaces, a simple technique for modifying a representation to search only rich parts of a larger search space, and representations that are highly expressive and so exhibit highly restricted and consequently enriched search spaces.
