GameScience was one of the very first manufacturers of RPG gaming dice in the industry, founded in 1974, and GameScience founder Lou Zocchi takes credit for manufacturing the first RPG dice for the Dungeons & Dragons boxed set.

GameScience is known for their Precision Dice as well as for their odd-sized dice, and was bought by Gamestation in March of 2009. Gamestation is a gaming retailer based in Kentucky with a large online presence and a significant presence in the poker supplies market.

GameScience Precision Dice

GameScience dice, according to Lou Zocchi, are made with a higher quality of plastic materials than other gaming dice, which gives them a more lustrous, almost gemlike quality.

What they are known for is the sharply defined, razor-like edge to the dice. This is achieved because the dice do not undergo the tumbling process that is used on most dice and is a part of the inking process. As a result GameScience dice not only have the characteristic sharp edge, but also come uninked. The number are still set into the dice, but must be inked by hand by the gamer who buys the dice.

In addition to the sharp edges, GameScience dice have an extruding chunk of plastic, a sprue from where the dice were removed from the mold. This sprue is normally removed in the tumbling process; however since GameScience dice skip that process this sprue must also be removed by hand (via a small piece of sandpaper) or tolerated.

Lou Zocchi claims that the tumbling process of other dice manufacturers causes dice to have uneven sides and differently rounded corners — and this is demonstrably true, as Zocchi has shown fairly convincingly. He further claims that as a result the dice will not roll substantially close to true and only GameScience dice will actually give gamers something very close to a truly random distribution of numbers. However, while this claim has theoretical merit, there has yet to be any testing or evidence that demonstrates that other RPG dice do not roll close to true. As such Zocchi’s claim is thus far unproven.

Update: Awesome Dice blog has testing of GameScience dice vs Chessex dice over 10,000 rolls for statistically significant results. Neither dice rolled within the margin of error; however, GameScience mostly rolled closer to true, except for the 14. Unlike what Zocchi says in the video below, the sprue on GameScience dice does drastically affect the rolling, making the 14 result far less likely to come up.

Odd-Sized Dice

Zocchi is a fan of odd sized dice and GameScience sells a “Zocchi Pack” of 5 dice that come in d3, d5, d14, d16 and d24. While the d3 can come in handy for many games, there are no RPGs that actually make use of these other dice sizes, and they are purchased primarily for the novelty factor.

Zocchi also created the d100, a die that looks something like a very small golf-ball. The interior of the hollow die contains many small weights that prevent it from rolling endlessly, like a ball might. This spherical die has 100 facets, enabling gamers to roll a percentile roll without requiring two separate dice; however, it can be exceedingly difficult to read the result.

Shortly after the release of the d100, or Zocchihedron, it was demonstrated that the d100 did not roll evenly — some numbers would come up much more frequently. Zocchi then modified the numerical distribution across the die and changing the way the inner weightings worked to address this issue.
