うんすんカルタ

8 players · You and 3 AI partners against 4 AI · 8-deal match

1. 1

   Objective

   • Your partners sit at alternating seats: 0, 2, 4 and 6 form your team. Compete for nine tricks each deal. The higher total after eight deals wins; equal totals draw.
2. 2

   Setup

   • Use all 75 cards: 15 each of Pao, Isu, Koppu, Ouru and Guru. Deal clockwise from the dealer's left in three batches of three, nine cards each. Turn up the first of the three remaining cards: this Okie indicator's printed suit determines trump.
   • Starting at the dealer's left, each player may declare or pass. The holder of the printed trump suit's Robai may declare and take the indicator, or conceal their identity. If everybody passes, the dealer takes it. The recipient discards a nontrump and opens with a nontrump. Reveal the discard and two remaining cards with the opening lead. These side cards score no trick.

   Rank order

   • Trumps descend Sun > Un > Sota > Tenka > native trump Robai > Rei > Kaba > numerals. Tenka is Pao Robai, always belonging to trump. When Pao is trump it appears only once. Plain courts descend Sun > Un > Rei > Kaba > Sota > Robai, except plain Isu Robai ranks between 2 and 1.
   • Pao and Isu numerals descend 9 > 8 > … > 1. Koppu, Ouru and Guru descend 1 > 2 > … > 9. Different plain suits do not compete: only the led suit can win without a trump.
4. 4

   Playing a turn

   • Play one card clockwise. Before the first trump lead there is no following obligation. Trumps played to a plain lead remain face down until all eight cards are played. Highest trump wins. Without trumps the highest card of the led suit wins. The winner leads next.
   • Leading trump is Meri. You cannot voluntarily lead trump on the first trick. Trumps are face up and must be followed, including Tenka. A player whose only initial trump was Sun may retain that Sun when it is their sole remaining trump. After Meri, Monchi applies: follow the led suit when possible, or play any trump. When void, any card is legal.
   • The ninth trick reveals everybody's last card simultaneously and is resolved automatically. Trumps compete as usual. Without trumps the dealer's last card supplies the led suit. Players cannot react to another player's final card.
5. 5

   Scoring and ending

   • Each trick scores 1. Outside Meri, compare the winning trump to the strongest opposing trump. Sun–Un, Un–Sota, Sota–Robai, Robai–Rei, long-suit 2–1 or round-suit 8–9 transfers another 2 points from the opposing team. Tenka does not replace a native Robai in these combinations.
   • A ninth-trick combination transfers 5. An undeclared native trump Robai involved in Sota–Robai or Robai–Rei also transfers 5. These conditions do not stack. Other combinations still transfer 2. The teams' settlement scores sum to 9 per deal and may be negative.
   • The dealer moves left after each deal. Higher cumulative score after eight deals wins. This table draws on equal scores without an extension. Next deal retains scores. Restart clears them.
