顶部、底部、左侧、右侧和边缘基诺
简介
上下基诺 (Top Bottom Keno) 是一种基诺游戏，玩家可以选择 1 到 40 或 41 到 80 之间的数字。玩家将根据所选半区中出现的号码数量获得赔付。有时，玩家还可以投注左侧、右侧和边缘号码，这些号码也已标注。
规则
- 玩家必须选择“上”或“下”。如果玩家选择“上”，则必须覆盖 1 至 40 之间的数字。如果玩家选择“下”，则必须覆盖 41 至 80 之间的数字。
- 游戏将从编号为 1 至 80 的球池中随机且不重复地抽取 20 个球。
- 玩家将根据20个球抽签中落入其所选半区的球数获得赔付。这被称为“接球数”。赔付表示例如下。
下表列出了我所知的三种赔付表 (PT)。最下面一行显示的是玩家回报率 (RTP)。
