🎮 What is Omok?
Omok (also known as Gomoku or Five in a Row) is a strategic board game where
two players take turns placing stones on a board, aiming to be the first to create an unbroken line of five
stones horizontally, vertically, or diagonally. With thousands of years of history in East Asia including Korea,
Japan, and China, this game combines simple rules with deep strategy, making it enjoyable for beginners and
experts alike.
📋 Basic Rules
- Game Setup: The game uses a
15×15 or 19×19 board with black and white stones. God Game Platform uses a 15×15 board.
- Starting the Game: Black
moves first, and players alternate placing stones on intersections. Once placed, stones cannot be moved or
removed.
- Victory Condition: The first
player to create an unbroken line of 5 stones in any direction (horizontal, vertical, or diagonal)
wins immediately. Under Renju rules, Black must make exactly 5; an overline of 6 or more is a forbidden move
for Black, not a win.
- Forbidden Moves: God
Game Platform applies Renju rules. Black (the first player) is bound by forbidden moves — double-three
(3-3),
double-four (4-4), and overline (6+ stones) — and cannot play on those points. White has no
restrictions.
- Draw: If the entire board is
filled without a winner, the game ends in a draw.
💡 Winning Strategies
- Control the Center: Start by occupying the center of the board. Playing from the center
gives you attack opportunities in all 8 directions.
- Create Open Fours: Create a line of 4 stones with both ends open. Your opponent can only
block one side, guaranteeing your victory on the next move.
- Double Three (3-3) Attack: Create two open threes simultaneously. Your opponent can only block
one, making this a powerful offensive technique.
- Four-Three (4-3) Attack: Create a four and an open three at the same time. Your opponent must
block the four, allowing your three to become a winning four.
- Balance Attack and Defense: Always block your opponent's three-in-a-row while building your own
attack lines. Focusing only on offense leaves you vulnerable to counterattacks.
- Watch the Diagonals: Horizontal and vertical lines are easy to spot, but diagonal
connections are often overlooked. Always check diagonal directions.
🏆 Tips for Beginners
- Check your opponent's stone placement every turn. Always block when they have three
in a row.
- Don't focus solely on attack. Develop a habit of thinking about both offense and
defense.
- Place stones where they can connect in multiple directions simultaneously.
- Read your opponent's patterns and defend preemptively to create comeback
opportunities.
- Practice against AI in various situations and review your games to improve.
❓ Frequently Asked Questions (FAQ)
Q: 五目並べと連珠（Renju）の違いは何ですか？
A: 五目並べは基本ルールのみ適用された自由対局版で、連珠は黒の先攻有利を補完するため三三（3-3）、四四（4-4）、長連（6個以上）の禁じ手ルールが適用される公式競技用ルールです。God Game Platformは連珠ルールを採用しているため、黒石に禁じ手が適用されます。
Q: 先攻の黒は常に有利ですか？
A: はい、一般的に先攻（黒）がやや有利です。理論的に完璧にプレイすれば黒が勝てると言われています。これを補完するためプロの試合では黒に禁じ手ルールを適用したり、スワップ（Swap）ルールを使用します。
Q: AI難易度はどう違いますか？
A: Easy（簡単）は初心者用で基本的な守りのみ行います。Medium（普通）は一般プレイヤーレベルで、基本的な攻撃と守り戦略を使用します。Hard（難しい）は高度な戦略とパターン認識を使用し、かなりの実力が求められます。
Q: オンライン対戦はどうやりますか？
A: 「Quick Match」ボタンを押すと自動的に似たレベルの相手を見つけてマッチングします。または「Create Room」で部屋を作って友達を招待したり、部屋リストから好きな部屋に参加できます。
Q: foスコアとは何ですか？
A: foはGod Game Platformのレーティングスコアです。勝利すると上がり、敗北すると下がります。相手との実力差によって変動幅が異なり、foスコアが高いほど実力が高いことを意味します。
