High-Low

Got distracted this morning looking at dice games and I found one that would be really simple to include in an RPG. High-Low is a very simple game, but I hacked up a version that could be played by a table of players (in game or IRL). Everyone places a bet in center of the table and then holds their open hand on the tabletop; palm up for High, palm down for Low. Then the shooter rolls the dice.

If the results are between 2 and 6, all players with palms down (Low) split the pot.
If the results are between 8 and 12, all players with palms up (High) split the pot.
If the result is 7, the shooter takes the pot.
If the result is doubles, winners are determined by whether the roll was high or low as above. Then, the shooter must pay out seven coins to each winner.

The shooter rotates every three throws, to keep things fair.  A person may stay in the game but abstain from betting in a round by making a closed fist. Typically, bets are low, to encourage speedy play and simplify splitting the pot.

I want to introduce this game by having an NPC teach it to the PCs. Commoners would use copper coins, soldiers would use silver, and merchants might use gold coins. I imagine more complicated games might be in use by the nobility.
