Yutnori originated in the ancient farming communities of Buyeo in 57 BCE where the livestock influenced each of the five possible moves: do is a pig, gae is a dog, mo is a horse, yut is a cow, and geol is a goat. The game’s basic concept is the following: throw the four provided sticks repeatedly and the first player to make his/her way around the board, returning to the start, wins. Each time one throws, the combination of the sticks’ landings (up or down) determines the type of move.

The digital version of Yutnori is a 2D, two-player board game with graphics hand-drawn through the program, Procreate. The players’ movements around the board were coded through Waypoints (empty objects serving as placeholders) and coroutines were utilized to track each throw. I ran into countless bugs primarily when implementing Yutnori’s unique set of rules. In order to identify them, I conducted several functionality tests, comparing expected results with experimental ones. From there, I was able to brainstorm viable solutions and implement them into the game.
