About Reversi

Reversi (Othello) on HT Hub is a 3D Three.js implementation with a felt-textured 8×8 board and corner pegs. Discs are 3D cylinders (one side black, one white) that rotate 180° on flip with smooth 300ms animation + cinematic lift. Place a disc to flip opponent discs sandwiched between yours. Translucent ghost discs on hover show legal moves. Four AI tiers: random / greedy max-flips / 4-ply minimax with positional weights (corners = 100, edges = 10, X-squares = -50) / 6-ply minimax with alpha-beta + transposition table. 2-player pass-and-play. Pass detection notice when a player has no legal move.
