The plan is that there is a "banker/dealer/roller" so to speak, someone that doesn't participate in the game itself. Here is a fleshed-out example where I am the dealer with two players participating (up to five can play):
Start
Dealer: Jamesie
Player A
Player B
Dealer setup
Dealer rolls sets of random dice and posts values to each player. Each player starts with five dice. I created a quick little app that rolls the dice for us if anyone is interested otherwise these can be rolled by a few sites online.
Player A (sent to Player A by the Dealer so only the Dealer and Player A know the values):
Player B (sent to Player B by the Dealer so only the Dealer and Player B know the values):
Banker decides on who plays first (unless one of the players from a previous game was the winner in which case the challenger). Let's say Player A goes first in which case they would reply to the topic with their guess. Here are two possible ways how this first round might play out:
It could be slow if people are offline between rounds however this could either be part of the fun or we could have an automatic discard of a players dice if they fail to play a round - say after a day or so of not responding.
