This skill is used to increase a character's chances of winning at games of chance. This skill doesn't affect games that are purely random, but does influence games with an element of skill, like sabacc. When playing a skill game honestly, all characters make opposed skill rolls, and the highest roll wins.

A character can also use the gambling skill to cheat or detect others who are cheating. When a character cheats, every other character is allowed to make an opposed gambling skill roll to see if they detect the cheat. The characters can make detection rolls every time the gambler attempts to cheat. If they fail, the gambler "wins" the round.

Modifiers include "assistance" (more than one person looking for the cheater, or helping the cheater), one character's familiarity with the game being played surpasses the other's, etc. The gamemaster should consider as many "angles" as possible when using the gambling skill.
