More built in
A focused board with thoughtful rules.
The simple surface is backed by game-state detail, rule enforcement and multiplayer coordination taken directly from the app.
Classic 15×15 board
Black opens the game. Move count, current turn and the last move remain visible, and a completed five-stone winning line is highlighted on the board.
Threat-aware AI
The AI evaluates attack and defence patterns including live fours, rush fours, live threes and compound threats, then searches candidate moves for a practical response.
Forbidden-move enforcement
Black-move rules detect overlines, double fours and double threes. The same restrictions are considered by the AI when it chooses a legal move.
Choose black or white
In Human vs AI mode you can choose which colour to play. Same-device mode supports two players, and non-network games include undo.
LAN rooms with match control
Host or find a nearby room, enter a player name and let the host start the match. A new network game begins only after the other player agrees.
Responsive and multilingual
The board adapts between portrait and landscape layouts, includes move and result sounds, and supports English plus Simplified and Traditional Chinese.
Strategy without ceremony
Open the board and make your move.
The rules are immediate: create an unbroken line of five stones before your opponent does.
Choose a mode and colour
Select AI, same-device or nearby multiplayer. Against AI, decide whether you want the opening black stones or white.
Build threats, block theirs
Balance attack and defence while the app tracks turns, legal moves, move count and the emerging winning line.
Review the result and play again
Victory, forbidden-move loss and draw states are clearly identified, with a direct path into the next match.
