清一色ゲーム - Chinitsu Game
Players: 2
Equipment: All the tiles from two suits. (Not honours)
Setup: Each player takes all the tiles of one suit and shuffles them face down in front of them. They then draw 15 tiles at random from this pool and build a Chinitsu ready hand with them, discarding the two unused tiles face down off to one side. After both players have built their hands they swap the remaining pool of tiles for their opponent's ones.
Play: Players Janken(Rock, Paper, Scissors) to decide who goes first. They look at the tiles they received from their opponent and try to figure out what their waits are. The player to lose the Janken discards first, and they then proceed to discard in turn till someone discards one of their opponent's waits. At which point the opponent Rons and wins.
There are a couple extra rules that can be use if desired:
Cancel (aka Mulligan): Once per game, during the hand building stage, a player is allowed to return all 15 tiles to their pond, shuffle and draw 15 new tiles.
Time Limits: Time limits can be placed on thinking time for discards or hand building of desired. It is likely that the first discard will have the longest thinking time, so maybe a limit on this stage is most likely.
Coin Toss: You can always replace the Janken with a coin toss or something similar. It was a Janken when I watched mostly because the Japanese decide everything by Janken. (probably even a civil war world be decided this way of one broke out today
)
). There might be some minor differences I forgot since I only played one hand or two, didn't writer the rules down and didn't play since, but it was pretty close...
