   Objective

   • Once you make a scoring combination, stop to collect all your combination points or call Koi-Koi to continue. Those points remain at risk: if your opponent stops first, you score zero. If both hands run out with no one stopping, all unclaimed points are lost and the deal is drawn.
2. 2

   Setup

   • Use all 48 flower cards. Deal eight cards to each player and eight face up to the board, leaving a 24-card face-down stock. The starting player is chosen randomly. Four cards of one month or four pairs on the board require a redeal. Either combination in a player's initial hand wins six points immediately. If both players have one, redeal.

   Playing a turn

   • Select a hand card, then confirm. If the board has no card of that month, leave it on the board. With one match, capture the pair. With two, choose one. With three, capture all four cards of the month.
   • Then reveal the top stock card and match it using the same rules. If two matching board cards are available, select one and confirm. Check for yaku only after both the hand-card and stock-card steps.

   Scoring and ending

   • Five brights score 15. Four brights score 10 without the willow rain man or eight with it. Three brights without the rain man score six. Count only the highest bright combination. Boar, deer and butterfly score five. The three poetry ribbons from pine, plum and cherry score six, as do the three blue ribbons from peony, chrysanthemum and maple.
   • Five animals, five ribbons or ten plains each score one, plus one for every additional card in that category. The chrysanthemum sake cup counts as both an animal and a plain. Different yaku scores add together.
   • At the end of a turn, a new yaku or increased total offers a choice to stop or call Koi-Koi. After continuing, your total must increase again before another choice appears. A yaku made on the final turn can still be cashed in.
