Rules Gimmicks are changes and addition to the game rules that are
invented on the fly as needed and added to your game for 1 Coin.
Add-ons are Rules Gimmicks that have been written down and
standardized so that they can be reintroduced into future games
without needing to be completely reinvented.
Some of these are just minor rules tweaks. Some will cover
special situations that may arise in the game better than the core
rules cover them. Some completely alter the way the game is
played.
If you've created interesting Rule Gimmicks in your game, let
us know, we'd love to see them.
