jackpot（n.）
“大奖”（jack-pot）一词最早见于1944年的老虎机（slot machine）术语，源自于已废弃的扑克（poker）术语（1881年），指当没有玩家手中牌为一对 J（jacks）或以上时开始的下注。其中 jack （名词）意为打牌的意义， pot (名词1) 指开始下注的意义。早期在犯罪俚语中，“大奖”一词指的是“麻烦”，特别是“逮捕”（1902年）。
The regular Draw-Poker game is usually varied by occasional Jack-Pots, which are played once in so many deals, or when all have refused to play, or when the player deals who holds the buck, a marker placed in the pool with every jack-pot. In a jack-pot each player puts up an equal stake and receives a hand. The pot must then be opened by a player holding a hand of the value of a pair of knaves (jacks) or better. If no player holds so valuable a hand the deal passes and each player adds a small sum to the pot or pool. When the pot is opened the opener does so by putting up any sum he chooses, within the limit, and his companions must pay in the same amount or "drop." They also possess the right to raise the opener. The new cards called for are then dealt and the opener starts the betting, the play proceeding as in the regular game. [Encyclopaedia Britannica, 11th ed., 1911, "Poker." The article notes "Jack-Pots were introduced about 1870."]
常规抽扑克游戏通常会在玩几局后时不时地进行 Jack-Pots，或当所有人都拒绝参加时，或由玩家发牌的时候，他所持有的资源为 buck，即奖池中的标记。在奖池中，每个玩家都出同样的赌注并获得一手牌。此时，必须由某位玩家以一对 J（jacks）或以上的手势打出 opened 才能打开奖池。如果没有人持有如此高价值的手牌，则交易（deal）过去，每个玩家向奖池中添加一小笔钱。当奖池被打开时，开启者将在规定限制内任意投放一定金额，然后他的朋友就必须支付同样的金额或者“放弃”，他们还有权利在开放者的基础上加价。然后，发新牌并由开启者开始下注。游戏进行方式和普通游戏一样。 ["Poker."， Encyclopaedia Britannica，第11版，1911年。该文章还指出，“大奖”游戏在1870年左右开始流行。]
