Ssangryuk (Korean Backgammon)

Record vs AI

Rules

Ssangryuk (쌍륙) is a Korean dice game played since the Three Kingdoms period. Be the first to move all 15 pieces off the board to win.

Roll two dice and move pieces by those numbers. You can use both numbers on one piece or split them between two.
Pieces never move backward. White (you) moves from point 24 toward point 1.
A point can hold at most 5 pieces.
You cannot land on a point with two or more opponent pieces. A single opponent piece there is captured and sent to the resting area in the middle.
On doubles, you move that number twice (two pieces).
If you have a captured piece, no other piece can move until it re-enters at its starting area (the opponent's side).
Once all 15 pieces are in your home (the 6 points at bottom right), you bear them off. When bearing off, leftover dice values are fine.
You may skip your turn before rolling.

How to play

Roll dice, tap a piece with a yellow outline, then a green highlighted point. Press Confirm when done; you can Undo before confirming.

Rules follow the eight rules on the Ministry of Culture, Sports and Tourism's children's site (문화체육관광부 어린이 누리집). Where sources are silent we chose: the widely used starting setup (the same 2-5-3-5 layout as backgammon; the Encyclopedia of Korean Culture also mentions a regional 16-piece layout), and you must use the dice whenever possible. Capture rules vary between sources (some say you need matching dice to capture), so we follow the most widely described method. Details differ by region.
