Wang et al.: Gauging Tetris Block Puzzle Difficulty by How Fast a Strong AI Learns — Fukai Reads
An arXiv preprint from a National Yang Ming Chiao Tung University and Academia Sinica group that measures the difficulty of the popular mobile game Tetris Block Puzzle. It rates rule variants by how fast and high a strong AI (Stochastic Gumbel AlphaZero) can learn to play, finding that more holding/preview blocks make the game easier while adding block shapes makes it harder (the T-pentomino most of all).
