It works like that in CP2020.
- Automatic Fail (when you roll 1), after which you need to a roll again in order to find out how bad the result of your fumble will be.
- Critical Success (when you roll 10), where you are able to roll an extra die and can sum up the results of both rolls, allowing you to do better than you'd normally be able to.
There is also:Here's an example; Johnny Silverhand needs to break into a locked room, a task the Referee considers to require some training. As such, it has a Difficulty of 15. Johnny's most applicable stat if Technical, because this is a Task that requires manipulating a mechanical object. Johnny isn't much of techie (his Tech stat is only +3, enough to fix guitar strings and plug in his amp). But Johnny also picked up Pick Lock +3 as one of early Pickup skills. This gives him a Base Ability of 6. Johnny will need roll at least a 9 to pick this lock.
