Jyugosai

In Jyugosai, a.k.a. 十五賽 (15 Dice), players take turns placing a die, then placing it on the intersection of lines on a Go-style board. When a player rolls a 6, they can either place it on the board as a 3 or roll it again, placing it on the board only if the result is a 6 and removing it from play otherwise. As soon as a player has a line of dice that sum to 15 or show three 1s, they win the round. The first player to win two consecutive rounds wins the game.
