Yacht: the public-domain ancestor — same three-roll structure, simpler scorecard, no bonuses.; Triple Yahtzee: three scorecards played simultaneously, with column multipliers.; Solitaire Yahtzee: the same game played alone against a target score.
Why people argue about this
People often assume that in Triple Yahtzee, each player is competing against one another like in a traditional game of Yahtzee, but actually, it's designed for players to compete simultaneously with their own scorecards, aiming to beat a predetermined target score across all three games played at once. This leads to misunderstandings about the nature of competition and scoring.
