Because Shotgun is a living entity and is constantly evolving for the greater benefit of mankind, new rules need to be created regularly. Anyone is welcome to implement their own rule if the situation arises. New rules often need to be created following a major discrepancy. The important thing to remember about this process is that the new rule does not take effect until the next car ride.
We try to keep these Official Shotgun Rules as simple and straightforward as possible. As with all things, simpler is usually better. If you have a new rule (or a modification to an existing rule) that you would like to propose, we would love to hear it.
