In the game of 9s, your abilities and skills are measured by how many "9s" you are good at it.
0 means you are between 10% and 90% in the skill or ability.
1 means you are above 90% of the population.
2 means you are above 99% of the population.
3 means you are above 99.9% of the population.
4 means you are above 99.99% of the population.
-1 means you are below 90% of the population.
-2 means you are below 99% of the population.
-3 means you are below 99.9% of the population.
etc.
To determine the victor in a contest (be it against another being or the environment) you roll 1d6 plus your modifier, against 1d6 plus their modifier or the modifier of the problem. A tie means a stalemate; often this means an immediate reroll, but if one party or the other has time on their side or another advantage, they win the tie.
If your difference is 5, you automatically win.
If your difference is 4, your win rate is 32:1. Every 32 times the +4 wins the +0 wins once, on average.
If your difference is 3, your win rate is 10:1.
If your difference is 2, your win rate is 4:1.
If your difference is 1, your win rate is 2:1.
If your difference is 0, your win rate is 1:1.
Now, not all problems are dominated by skill this much. For situations where chance matters less, you can use a smaller die; for example, a formal competition of Strength, you might use 1d4. For situations where chance matters more, you can use a larger die.
The goal is to minimize the amount of chaff on a character sheet. Every +1 is large and impactful.
