經典街機，完美重現
《小精靈》（Pac-Man）由 NAMCO 於 1980 年推出，是史上最具代表性的街機遊戲之一，全球銷售超過 4 億套。本網頁版高度仿真原版 28×31 格迷宮、244 顆豆子（含 4 顆能量豆），以及四隻性格迥異的鬼魂 AI，讓玩家無論身在何處都能重溫那份純粹的街機快感。
玩法規則
- 使用方向鍵（電腦）或滑動螢幕（手機）操控小精靈在迷宮中移動。
- 吃光迷宮內所有 240 顆普通豆子即過關，挑戰下一關。
- 吃下四個角落的「能量豆」，鬼魂會變成藍色驚嚇狀態，此時可以反過來追吃牠們。
- 連續吃鬼得分為 200、400、800、1600 分，越吃越划算。
- 被鬼魂碰到則失去一條生命；累計得分達 10,000 分時獲得額外生命。
- 每關開始後迷宮中央會於特定時機出現水果，吃掉可獲得高額獎勵分數（從 100 分的櫻桃到 5,000 分的鑰匙）。
四隻鬼魂的獨特個性
| 名稱 | 顏色 | 策略 |
|---|---|---|
| 影子（Blinky） | 紅色 | 永遠直接追蹤你目前的位置，越到後期越兇猛（Elroy 模式加速）。 |
| 飛毛腿（Pinky） | 粉色 | 預測你前進方向的四格，繞路堵截。 |
| 善變（Inky） | 青色 | 以紅鬼位置為基準計算目標格，行蹤難以預測。 |
| 膽小（Clyde） | 橘色 | 距離小精靈超過 8 格時追近，低於 8 格時反而逃回角落。 |
進階技巧
鬼魂在「巡邏模式」與「追逐模式」之間週期性切換，切換瞬間會掉頭，善用此時機可安全通過危險地帶。能量豆的驚嚇時間隨關卡推進而縮短，第 17 關起鬼魂不再變藍，需要更精準的走位。
遊戲特色
- 完整還原原版速度曲線：玩家速度 80%→100%，鬼魂速度 75%→95%，隧道穿越時鬼魂大幅減速。
- 原版巡邏／追逐時間表（第 1 關 7-20-7-20-5-20-5 秒，第 5 關起縮短）。
- Web Audio 即時合成音效，無需下載音訊資源。
- 進度與最高分自動存入 localStorage，下次開啟即可查看。
- 看激勵廣告可獲得一次復活機會。
- 支援鍵盤（方向鍵 / WASD）及觸控滑動兩種操作方式。
The Iconic Arcade Classic, Faithfully Recreated
Pac-Man, released by NAMCO in 1980, is one of the best-selling and most recognizable video games in history, with over 400 million units sold worldwide. This browser-based remake faithfully reproduces the original 28×31-tile maze, 244 collectibles (240 dots + 4 power pellets), and the four uniquely scripted ghost AIs — delivering the pure arcade experience right in your browser, on any device.
How to Play
- Use the arrow keys or WASD (desktop) / swipe the screen (mobile) to move Pac-Man through the maze.
- Eat all 240 regular dots to complete the stage and advance to the next level.
- Grab one of the four corner "Power Pellets" to send ghosts into a frightened (blue) state — then eat them for bonus points.
- Consecutive ghost eating scores: 200 → 400 → 800 → 1,600 points.
- One life is lost each time a ghost touches Pac-Man; earn an extra life at 10,000 points.
- A bonus fruit appears near the center of the maze at key intervals — worth 100 (cherry) up to 5,000 (key) points depending on the current level.
Four Ghosts, Four Personalities
| Name | Color | Behavior |
|---|---|---|
| Blinky (Shadow) | Red | Directly chases Pac-Man's current tile; activates Elroy speed boost at low dot counts. |
| Pinky (Speedy) | Pink | Targets four tiles ahead of Pac-Man's direction to cut off escape routes. |
| Inky (Bashful) | Cyan | Uses a vector from Blinky's position to calculate an unpredictable target tile. |
| Clyde (Pokey) | Orange | Chases when more than 8 tiles away; retreats to its scatter corner when close. |
Advanced Strategy
Ghosts alternate between Scatter mode (heading to corner targets) and Chase mode on a fixed schedule; they always reverse direction at each mode switch — use these brief windows to slip through danger zones. Fright duration decreases each level, reaching zero at level 17, where power pellets only reverse ghosts instead of making them edible.
Key Features
- Accurate speed curves: Pac-Man 80%→100% base speed; ghosts 75%→95%; tunnel slowdown for ghosts.
- Authentic scatter/chase timing schedules matching the original arcade ROM.
- All sound effects synthesized via Web Audio API — zero audio asset downloads.
- High score persisted in localStorage across sessions.
- Revive once per game by watching a rewarded ad.
- Full keyboard (arrow keys / WASD) and touch-swipe support.
