Riichi mahjong is a four-player tile game involving strategy, probability, and imperfect information. I play both online and in New York City. I placed 2nd in the Intercollegiate Riichi Mahjong Open Finals in 2025, which qualified me for a seeded entry in the 2026 Ryuousen USA Qualifiers.
I also enjoy exploring mahjong from a computational perspective for fun. Its combination of imperfect information and stochasticity makes it interesting from the perspective of AI and reinforcement learning. Recently, I have been playing with Mahjax: A GPU-Accelerated Mahjong Simulator for Reinforcement Learning in JAX.
I am also building a small website for mahjong analysis and tools. Check it out here:
