1. The rules of the game should be given or explained to everyone given a coin. It’s rude to call out a challenge if you haven’t broken down the way it works ahead of time.
2. Coins must be carried at all times, and challenges can be called out anywhere and at any time. You can only take four steps in order to reach your coin.
3. The challenger must clearly state whether the challenge is for one drink or a round of drinks.
4. If the person challenged fails to produce the coin, the challenge must be honored, and drinks must be purchased. Each person can only be challenged once.
5. If everyone who is challenged manages to produce a coin, the challenger is on the hook to buy the drinks. Be careful of who you challenge.
6. Never hand someone else a coin in response to a challenge. Doing so is the same as giving the person the coin. The coin can be placed on the table, and anyone who wants to examine it is honor-bound to return it to its original location.
7. If you lose your coin, you’re responsible to replace it as soon as you possibly can. Losing your coin doesn’t absolve you from responsibility to follow the rules of the game. In other words, you’re buying a lot of drinks if you lose it.
8. There are zero exceptions to these rules. They apply whether you’re wearing clothes or not, so think ahead. Remember, you’ve got four steps to get within arm’s reach of your coin.
9. A challenge coin is a coin. It’s not a belt buckle or bracelet or necklace, so don’t use it like one. The exception is for coins that are carried in a pouch around the neck.
10. You must control your coin at all times. It indicates honor, so you shouldn’t give it to just anyone.
11. You may not drill holes in your coin.
12. These rules apply to anyone worthy to be given a coin, anyone who’s known to own a coin, and anyone who buys a coin.
