Yathzee [sic] is one of many ports of the dice game Yahtzee to the Commodore 64. The goal of the game is to score as many points as possible by rolling five dice to make certain combinations. Points are earned depending on the scoring category chosen. A Yahtzee is when all five dice have the same number and is worth 50 points, the most of the categories. Unique to this particular port is the usage of a synthesized voice, which sounds pretty rough due to being on an 8-bit computer.
nymx decides to max out and glitch the score counter by consistently scoring Yahtzees many times in a row. The synthesized voice was kept in to showcase its ability, despite being able to save an additional 43 seconds with it turned off.
