Conspiracy X isn't strickly diceless but it can easily be if characters play to their strengths.
As if your skill is great than the difficulty you automatically succeed. If you take time, you can reduce the difficulty by one. If you have help from an equally skilled person you can also reduce the difficulty by one.
Since skills range from 1 to 5 and difficulties from 1 to 6 (6 being very rare), most of the time if you are doing something you are good at you never need to roll.
Also if your skill it 2 less than the difficulty you automatically fail, so you might as well not even attempt something really hard if you aren't highly skilled.
