Graph‑T is a card game where the power of each card isn't derived from numbers but from the height of the graphic printed on its face. Each deck contains cards of several "suits" (colors) and a set of gray cards that act as wildcards. The goal is simple: build the tallest stack of cards from a single suit by the end of the game.

The game follows the classic trick‑taking structure. At the start of each round, the player to the left of the dealer leads a trick with any card. The other players must follow the suit that was led, unless they have no cards of that suit. If they can’t follow, they may play a gray card – but only if the preceding card was gray or contained gray. When a gray card is played, the player who played it takes on the role of the trick leader, and the trick ends once all players have played. The trick winner is the one with the highest card of the leading suit, or a gray card if all cards are gray. The winner collects all the cards from the trick, but only keeps the cards of the leading suit; the rest are discarded to the center.

Throughout the game, each player tries to accumulate tricks of a single suit. When everyone’s hand is gone, each player compares the tallest stack they managed to build from one suit. Cards are stacked one on top of another, so the total height of the stack determines the score. The player with the tallest stack wins the game.

Graph‑T blends the tension of a traditional trick‑taking game with the novelty of cards that feature visual "graphics." The rule of following suit keeps the strategy alive, while the gray cards add a surprise element that can flip the game in an instant. Balancing the prediction of opponents’ cards with the chance to play a gray card makes this experience appealing both to fans of classic card games and to those looking for something more visual and dynamic.
