**Trirhombus Game Rules Introduction**



Trirhombus is an abstract game I invented in 2021, with a major rules update in January 2024. It uses three rhombi to represent three faces of a cube, with scoring from the different perspectives of the two players—the rules are designed very cleverly.



The number of pieces has also been carefully researched and tested. If there are too many pieces, players will simply build a large area in their own territory without engaging the opponent in combat. Too many pieces also make the game last too long.



At the start, both players place different pieces, which effectively avoids creating rotationally symmetric positions.



However, there is no proven winning strategy for either the first or second player in this game.
