Connect Four on a 9x8 board against a neural net, in the browser (line4-9x8.com)

Line4 9x8 has launched a free online version of the classic four-in-a-row game, with a twist: players compete against a neural network AI on a larger 9x8 board. This new format introduces greater complexity and strategy, enabling deeper traps and long-term planning, making it significant for the AI and machine learning community as it demonstrates advanced applications of neural networks in interactive gaming. The AI opponent, available in varying difficulty levels, utilizes a combination of neural network training, value-guided search techniques, and an extensive opening book, similar to what powers its Android app counterpart. The game also offers players the chance to sharpen their skills with 20 solver-verified puzzles designed to enhance strategic thinking and adaptability against AI opponents. With no ads or tracking, users can enjoy an uninterrupted experience while tracing their progression through an impressive Elo-style ranking system that benchmarks performance from Beginner to Grandmaster levels. This initiative not only engages players in a fun and challenging way but also showcases the practical implications of AI in game development, pushing the boundaries of interactive AI tools in everyday platforms.
