貪食蛇的規則是什麼？

控制蛇在棋盤上移動，吃到食物（通常是蘋果）後蛇身變長並得分。遊戲結束條件：(1) 蛇頭撞到自己的身體；(2) 蛇頭撞到牆壁邊界。目標是在越來越長的蛇身限制下盡可能長時間存活並累積高分。

Control a snake moving around the board. Eating food (usually an apple) extends the snake’s body and earns points. Game ends when: (1) the snake’s head collides with its own body; or (2) it hits a wall. The goal is to survive as long as possible and score as high as you can as the snake grows longer.

如何在手機上操作？

在手機上點擊遊戲區域中相對蛇頭的目標方向即可轉向（例如點蛇頭右側就往右轉）。桌機上使用鍵盤方向鍵或 WASD 鍵操作。注意：蛇不能直接 180° 反轉（如向左移動時不能直接向右），只能轉向垂直方向。

On mobile, tap the play area toward your target direction relative to the snake’s head (e.g. tap to the right of the head to turn right). Desktop players use arrow keys or WASD. Note: the snake cannot reverse 180° — if moving left, you can’t immediately go right. Only perpendicular turns are allowed.

有什麼技巧可以拿高分？

高分技巧：(1) 保持蛇的移動有規律，如沿邊緣繞圈後向內盤旋，避免蛇身混亂；(2) 食物出現後不要急著衝過去，先確認路徑安全；(3) 蛇身較長時，預留足夠的「逃生路線」空間；(4) 避免在棋盤中央迂迴，容易自我截斷退路；(5) 速度提高後加強預判反應而非等出現才轉向。

High-score tips: (1) Move systematically — serpentine patterns along edges prevent self-trapping; (2) Don’t rush at food — verify the path is clear first; (3) Keep escape routes open as the snake grows longer; (4) Avoid zigzagging in the center — it cuts off your own path; (5) At higher speeds, anticipate turns early rather than reacting after seeing the obstacle.

速度會自動加快嗎？

是的，吃到食物後蛇的移動速度會逐漸加快，增加遊戲難度。速度提升是貪食蛇的核心挑戰機制——越長的蛇加上越快的速度，考驗玩家的反應速度和路徑規劃能力。高手通常在最高速度下仍能保持系統性移動而不慌亂。

Yes, the snake speeds up progressively as it eats more food, increasing difficulty. Speed escalation is the core challenge mechanic — a longer snake at higher speed tests both reaction time and route planning. Expert players maintain systematic movement patterns even at maximum speed.

貪食蛇是哪裡起源的？

貪食蛇概念最早可追溯至 1976 年的街機遊戲 Blockade。1997 年，Nokia 將 Snake 預載於 Nokia 6110 手機，成為全球最廣為人知的手機遊戲之一，估計有超過 3.5 億台 Nokia 手機搭載此遊戲。這款遊戲讓許多人第一次接觸到電子遊戲，具有重要的文化地位。

Snake’s concept traces back to the 1976 arcade game Blockade. In 1997, Nokia pre-installed Snake on the Nokia 6110, making it one of the most widely played mobile games ever — estimated to have shipped on over 350 million Nokia devices. For many people, Snake was their first video game experience.

遊戲結束後可以立即重新開始嗎？

可以。遊戲結束後會顯示結果畫面，點擊「重新開始」即可立即開始新一局，蛇的長度重置為初始狀態，分數歸零。本遊戲的節奏設計就是快速的「一局又一局」體驗——每局只需幾分鐘，非常適合短暫休息時玩一局再回去工作。

Yes. After game over, a results screen appears; click "Restart" to begin a new game immediately with the snake reset to starting length and score at zero. The game is designed for quick "just one more round" sessions — each game takes just a few minutes, perfect for short breaks.
