實現一個完整且復雜的升級游戲涉及到很多方面，包括玩家操作、游戲狀態管理、游戲規則和邏輯等等。下面是一個較為簡化的升級游戲的代碼示例：

// 游戲狀態枚舉
const GameState = {
  NOT_STARTED: 'NOT_STARTED',
  BETTING: 'BETTING',
  PLAYING: 'PLAYING',
  END: 'END'
};

class Player {
  constructor(name, money) {
    this.name = name;
    this.money = money;
    this.hand = [];
  }
}

class Game {
  constructor(numPlayers) {
    this.numPlayers = numPlayers;
    this.players = [];
    this.state = GameState.NOT_STARTED;
    this.currentPlayerIndex = -1;
    this.round = 0;
    this.pot = 0;
  }

  // 開始游戲
  start() {
    if (this.state !== GameState.NOT_STARTED) {
      console.log('游戲已經開始！');
      return;
    }

    this.state = GameState.BETTING;
    console.log('游戲開始！');
    console.log('請玩家下注！');
  }

  // 玩家下注
  placeBet(playerIndex, amount) {
    if (this.state !== GameState.BETTING) {
      console.log('請等待其他玩家下注！');
      return;
    }

    const player = this.players[playerIndex];
    if (amount > player.money) {
      console.log('你沒有足夠的金錢下注！');
      return;
    }

    player.money -= amount;
    this.pot += amount;

    console.log(`${player.name} 下注了 ${amount} 元！`);

    // 檢查是否所有玩家完成下注
    if (this.players.every(player => player.money === 0)) {
      this.dealCards();
    } else {
      this.currentPlayerIndex = (this.currentPlayerIndex + 1) % this.numPlayers;
      console.log(`請 ${this.players[this.currentPlayerIndex].name} 下注！`);
    }
  }

  // 發牌
  dealCards() {
    this.state = GameState.PLAYING;
    console.log('正在發牌...');

    // 初始化牌組
    const deck = [];
    for (let i = 2; i <= 10; i++) {
      deck.push(i, i, i, i, 'J', 'J', 'Q', 'Q', 'K', 'K', 'A', 'A');
    }
    deck.push('小王', '小王', '大王', '大王');

    // 洗牌函數
    const shuffle = function (deck) {
      for (let i = deck.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [deck[i], deck[j]] = [deck[j], deck[i]];
      }
      return deck;
    }

    const shuffledDeck = shuffle(deck);

    for (let i = 0; i < this.numPlayers; i++) {
        const player = this.players[i];
        player.hand = shuffledDeck.splice(0, 17);
    }

    this.currentPlayerIndex = 0;
    console.log(`第 ${this.round + 1} 輪開始！`);
    console.log(`${this.players[this.currentPlayerIndex].name} 先行動！`);
  }

  // 玩家出牌
  play(playerIndex, cards) {
    if (this.state !== GameState.PLAYING) {
      console.log('請等待你的回合！');
      return;
    }

    const player = this.players[playerIndex];
    const currentPlayer = this.players[this.currentPlayerIndex];

    if (playerIndex !== this.currentPlayerIndex) {
      console.log('還沒有輪到你出牌！');
      return;
    }

    if (!this.isValidMove(cards)) {
      console.log('出牌不合法！');
      return;
    }

    player.hand = player.hand.filter(card => !cards.includes(card));
    currentPlayer.hand = currentPlayer.hand.concat(cards);
    currentPlayer.hand.sort((a, b) => this.getCardValue(b) - this.getCardValue(a));

    console.log(`${player.name} 出牌：${cards.join(' ')}`);
    
    if (player.hand.length === 0) {
      this.round++;
      
      if (this.round === 3) {
        this.state = GameState.END;
        console.log(`游戲結束！奪得最終勝利的玩家是 ${this.findWinner().name}！`);
      } else {
        this.currentPlayerIndex = (this.currentPlayerIndex + 1) % this.numPlayers;
        console.log(`第 ${this.round + 1} 輪開始！`);
        console.log(`${this.players[this.currentPlayerIndex].name} 先出牌！`);
      }
    } else {
      this.currentPlayerIndex = (this.currentPlayerIndex + 1) % this.numPlayers;
      console.log(`${this.players[this.currentPlayerIndex].name} 下一個出牌！`);
    }
  }

  // 尋找最終勝利的玩家
  findWinner() {
    let highestMoney = -1;
    let winner = null;

    for (let player of this.players) {
      if (player.money > highestMoney) {
        highestMoney = player.money;
        winner = player;
      }
    }

    return winner;
  }

  // 點數轉換函數
  getCardValue(card) {
    if (!isNaN(parseInt(card))) {
      return parseInt(card);
    }

    switch (card) {
      case 'J':
        return 11;
      case 'Q':
        return 12;
      case 'K':
        return 13;
      case 'A':
        return 14;
      case '小王':
        return 15;
      case '大王':
        return 16;
      default:
        return 0;
    }
  }

  // 判斷出牌是否合法
  isValidMove(cards) {
    // 檢查出牌是否符合規則
    if (!this.isStraight(cards) && !this.isSameRank(cards)) {
      return false;
    }

    // 檢查出牌是否大于上家
    if (this.currentPlayerIndex > 0) {
      const prevPlayer = this.players[(this.currentPlayerIndex - 1) % this.numPlayers];
      const prevCards = prevPlayer.hand.slice(0, cards.length);
      if (this.getCardValue(cards[0]) <= this.getCardValue(prevCards[0])) {
        return false;
      }
    }

    return true;
  }

  // 判斷是否是順子
  isStraight(cards) {
    if (cards.length < 5) {
      return false;
    }

    const values = cards.map(card => this.getCardValue(card));
    values.sort((a, b) => b - a);

    for (let i = 1; i < values.length; i++) {
      if (values[i - 1] - values[i] !== 1) {
        return false;
      }
    }

    return true;
  }

  // 判斷是否是相同點數
  isSameRank(cards) {
    if (cards.length < 5) {
      return false;
    }

    const ranks = new Set(cards.map(card => card.slice(0, -1)));

    return ranks.size === 1;
  }
}

// 運行游戲
const game = new Game(3);
game.players.push(new Player('張三', 100));
game.players.push(new Player('李四', 100));
game.players.push(new Player('王五', 100));
game.start();
game.placeBet(0, 30);
game.placeBet(1, 30);
game.placeBet(2, 30);
game.play(0, ['2?', '2?', '2?']);
game.play(1, ['3?', '3?', '3?']);
game.play(2, ['4?', '4?', '4?']);

在這個代碼示例中，我們定義了一個Game類來管理升級游戲的狀態和邏輯，使用Player類表示每個玩家。游戲開始后，玩家依次下注，下注完畢后進行發牌，然后輪流出牌，每輪出牌按照輪到玩家的上家的牌決定大小。游戲通過isValidMove方法判斷出牌是否符合規則和是否大于上家牌，根據規則進行判斷勝負，并最終決出最終勝利者。

這個示例中的游戲邏輯相對比較簡單，你可以根據自己的需求來修改和擴展代碼，實現更復雜的升級游戲。
