  This paper introduces ZeusAI, an artificial intelligence system developed to
play the board game 7 Wonders Duel. Inspired by the AlphaZero reinforcement
learning algorithm, ZeusAI relies on a combination of Monte Carlo Tree Search
and a Transformer Neural Network to learn the game without human supervision.
ZeusAI competes at the level of top human players, develops both known and
novel strategies, and allows us to test rule variants to improve the game's
balance. This work demonstrates how AI can help in understanding and enhancing
board games.
