About
Gomoku at Ply Yard is a small browser board for the part of five-in-a-row that gets interesting after the first easy moves: the crossing points, the forced replies, and the quiet stones that become a fork later.
One board, ready before the explanation
The board opens on the home page. You can play against the local computer opponent or choose Local and pass the device to someone beside you. There is no account step, lobby, ranking system, or download gate before the first move.
The game uses a 15×15 freestyle board. Black moves first; five or more connected stones win; Renju forbidden-move rules do not apply. Those choices keep the casual game clear while leaving enough room to practice genuine Gomoku ideas.
Tools are here for review, not for rushing
Undo, Hint, and replay are designed for the moment after a position surprises you. A hint can name a point worth considering. Replay lets you return to the turn before a forced sequence started. Neither tool replaces reading the board, and neither claims to provide a rated or tournament-grade analysis.
Difficulty levels are local practice settings. They are not ratings, matchmaking tiers, or a promise that a particular level will play the same way on every device.
Part of Ply Yard, not a game catalogue
Ply Yard is a small studio of browser boards. This Gomoku site keeps its own board, guides, visual language, and local game logic rather than turning every game into one large portal. The goal is a place you can reopen, understand quickly, and use for one more thoughtful game.
