It's quite simple: in most cases, such as when attacking an enemy, there's a comparison of stats. Revan randomizes numbers within a range from 1 to the value of the stat; in melee combat, this would be the corresponding dodge and accuracy. Whoever rolls higher wins. If a 1 is rolled, something bad happens (e.g., you drop your weapon, the accuracy roll fails).
As far as I know, the opposing pairs are as follows (Revan can correct me if I'm wrong):
Melee accuracy vs. melee dodge
Ranged accuracy vs. ranged dodge
Magic power vs. willpower
Magic accuracy vs. magic resistance
Stealth vs. perception
In some cases, a stat is used against a difficulty determined by the GM, rather than an existing characteristic of a living creature. For example, when trying to avoid boulders rolling towards you. But it works on the same principle, as far as I know. In other cases, new checks may be involved using existing characteristics. For example, a character with the second rank in one-handed weapons may make an accuracy check before dodging in melee combat and parry the opponent's attack.
That's how it works. I hope I haven't forgotten or confused anything.
