Description
A player rolls multiple dice and selects one based on a rule.
Discussion
The most common implementation of Dice Selection has players roll two dice and select the highest or lowest. Dungeons & Dragons uses this system and refers to the two states as “advantaged” and “disadvantaged.” An alternative is for players to roll three dice and to choose the median die. A High/Low selection is a way for designers to skew single die results fairly significantly toward the high or low end. Conversely, a median selection system makes extreme results unlikely. Result 1 die 2 dice, high (%) 2 dice, low (%) 3 dice, median (%)
The table above shows the chances of rolling different numbers with a standard die roll, rolling two dice and selecting the highest (or lowest), and rolling three dice and selecting the middle value. Rolling 2 dice and selecting the highest almost doubles the chances of a result of 6, and a result of 1 is 80% less likely than with a standard die roll. Selecting the middle out of 3 dice emphasizes results of 3 and 4, while cutting the chances of a 1 or 6 in half compared to a standard roll. Root presents a related system, where two dice are rolled for battles, with the Attacker taking the higher roll and the defender the lower. This encourages aggression.

描述
玩家掷多个骰子并根据规则选择一个。
讨论
骰子选择（Dice Selection）最常见的实现是让玩家掷两个骰子并选择最高或最低的。《龙与地下城》（Dungeons & Dragons）使用此系统，并将这两种状态称为“优势”（advantaged）和“劣势”（disadvantaged）。另一种选择是让玩家掷三个骰子并选择中间值。高/低选择是设计师将单骰结果显著偏向高端或低端的一种方式。相反，中间值选择系统使极端结果不太可能出现。
Result 1 die 2 dice, high (%) 2 dice, low (%) 3 dice, median (%) （结果 | 1骰 | 2骰取高(%) | 2骰取低(%) | 3骰取中(%)）
上表显示了标准骰子掷骰、掷两个骰子并选择最高（或最低）以及掷三个骰子并选择中间值的不同数字的几率。掷2个骰子并选择最高几乎使结果为6的几率翻倍，而结果为1的几率比标准掷骰少80%。从3个骰子中选择中间值强调了3和4的结果，同时与标准掷骰相比将1或6的几率减半。《Root》提出了一个相关的系统，其中为战斗掷两个骰子，攻击者取较高的掷骰结果，防御者取较低的。这鼓励了侵略性。
