Zilch is a Flash game that is based off of the dice game Farkle. Usually played by two or more people, each player takes turns rolling six dice. Every time the dice are rolled, the ones that form a scoring combination are set aside and the player has the option to either roll again with the remaining dice or stop and add up the points with the dice combos they have. If the next roll doesn't result in any scoring combinations, they lose all the points they made in that turn. In the Zilch variation, the game ends when any player manages to reach 10,000 points.
In this run, synabler wins a single game as fast as possible, which is done by rolling six 1s in one turn and four 1s in another. To pull this off, the RNG was thoroughly analyzed and later manipulated to get the desired rolls. For more details, you can read the author's notes.
Note: The game as shown in the movie is missing a few graphics due to imperfect emulation.
