Success
Your roll is a Success when the Result is greater than the Difficulty.
For unopposed rolls, a Result that is equal to the Difficulty is also a Success.
For opposed rolls, equal Results (ties) require a reroll from both sides.
Rote Actions
Cooperation
If Characters want to help each other perform a task, one of them acts as the leader and makes the roll, while the rest add their scores together as a Modifier to the leader's roll.
Adding your score as a modifier to the leader's roll requires that you contribute the same amount of time as everyone else participating in completing the task.
The Narrator should use their judgement to determine reasonable limits on how many Characters can effectively participate, and by how much these helpers might assist in completing the task more quickly than normal.
