This Stronghold game by Mike Fitzgerald is a trick-taking card game in which players collect Diamonds - not cards bearing that suit, mind you, but rather actual "Diamond Crystals". What makes the game of Diamonds different from other trick-taking card games is that when you cannot follow suit you get a "Suit Action" based on what suit you do play. Suit Actions are also taken by the winner of each trick, as well as at the end of a full Round of play. Whoever has the most points in Diamond Crystals at the end of the game wins!
The winner of this tournament will get a trophy, a copy of the game, plus a seat in the first elimination round of the Southwest Regional Championships to be held at GenghisCon (Denver, CO – February 2020), plus a badge to GenghisCon.
