Lou Zocchi is a legendary American tabletop game designer, precision dice manufacturer, and foundational figure in the early global tabletop role-playing game (TTRPG) and wargaming community, widely nicknamed the 'God of Dice' by long-time hobbyists.
Key moments
Zocchi addressed a critical unmet need in the 1970s TTRPG space, where most mass-produced polyhedral dice of the era were poorly molded, unevenly weighted, and generated skewed, non-random results that undermined game balance. His focus on strict precision calibration set a new quality benchmark for dice production that remains the industry standard decades later.
The distinct 100-sided Zocchihedron he designed has become a cult collector's item for dice enthusiasts across the world, with its unusual multi-facet shape recognized even by casual tabletop players as a symbol of experimental dice design. It is still widely used in niche wargaming, tabletop RPG, and educational probability contexts today.
His small U.S. dice and game firm GameScience is entirely unrelated to the prominent Chinese video game developer of the same English name that produced the 2024 hit Black Myth: Wukong, a frequent source of mix-up for cross-border gaming audiences.
Louis Zocchi (d. 15 April 2026) was a gaming hobbyist, former game distributor and publisher, and maker and seller of polyhedral game dice. In 1986, he was elected to the Charles Roberts Awards Hall of Fame.[1]
Lou Zocchi was one of the first editors for Avalon Hill
Zocchi also designed and published the Star Fleet Battle Manual (1977) miniatures rules, which he licensed from Franz Joseph, and in 1979 Zocchi's friend Stephen Cole licensed the rights from Joseph to publish the Star Fleet Battles game.[3] Zocchi also distributed the Wee Warriors line after 1977.[3] Zocchi helped Judges Guild with their financial difficulties in the early 1980s by paying them $350 every time they gave him the rights to reprint their out-of-print supplements.[3] Mike Hurdle of Holly Springs, Mississippi purchased Zocchi Distribution in February 1998.
Zocchi and his company Gamescience[4] have published a number of games over the years (many designed by Zocchi), but are best known for making dice and inventing the Zocchihedron (100-sided) die.
Zocchi has designed a few games himself, including Hardtack, and Battle Wagon Salvo.
In 1987, Zocchi was inducted into the Academy of Adventure Gaming's Hall of Fame.[2] He was honored as a "famous game designer" by being inducted into the Game Designers Hall of Fame and featured as the king of clubs in Flying Buffalo's 2009 Famous Game Designers Playing Card Deck.[5]
Gamescience is still trading, and (as of 2015) Zocchi is still active in the gaming community.
He later joined the Alabama State Defense Force and held the rank of Colonel.[2]
Most dice, according to Zocchi, do not roll accurately because of flawed manufacturing processes. The dice favor certain numbers and are more likely to land on those numbers. Zocchi believes the "superstition" of many gamers who use specific dice to roll high and others to roll low results from the fact that major dice manufacturers smooth out the straight edges of their dice in machines much like rock tumblers. The result is that plastic dice originally molded evenly are unevened and unbalanced, making them more likely to land on some numbers than on others.
Zocchi demonstrates the imperfections of dice with statistical results (showing uneven distribution of rolled die values) and with photographs of uneven die edges, faces and vertices. His demonstrations are sales pitches for his precision edged dice (with sharp edges) manufactured by his company, Gamescience. Tests by Jason Mills in 1987 and published in White Dwarf magazine showed that his Zocchihedron had a significantly uneven number distribution.[6] Right after that article came out, Zocchi adjusted the numbering of the Zocchihedron to correct the distribution and claims that the d100 now rolls rightly, whereas the original Zocchihedron had all the mid-range numbers clustered at the equator. The modified layout assigns one number from each tens-cluster to each ring of numbers around the die. Only white dice with black numbers use the older number distribution. Corrected dice are manufactured in other colors. However, while this "correction" will prevent the Zocchihedron from biasing against very high and very low numbers, the distribution of the individual numbers themselves will remain to be proven by tests.
Due to safety concerns, the 4-sided die (or d4) produced by Gamescience has truncated points.
Zocchi has invented and produced several "non-standard" dice. These are a 3-sided die, a 5-sided die, a 14-sided die, a 16-sided die, and a 24-sided die. All these except the 7-sided (d7) are available in high-impact translucent plastic. The 7 sided die was invented by Bernard Beruter of Canada.[7]
How to $ell Your Wargame Design is a book about how to successfully sell a board wargame design that was written and self-published by Zocchi in 1975.[8] As game designer Stephen V. Cole noted, Zocchi ran a seminar every year at Gen Con on "starting a game company and selling your wargame design."[9] Zocchi distilled this into a 16-page book that he self-published, How to $ell Your Wargame Design, with the intent to help other game designers get their games published.[8] The book includes a list of game publishers, as well as various publishing goods and services for the person wanting to self-publish.[8]
In Issue 35 of The Space Gamer January 1981), American game designer Steve Jackson noted the book's largest drawback was that it verged on being out of date: "Most of the basic advice is still sound, but many of the names on those lists are certainly obsolete. And don't take the copyright advice. The laws have changed since Lou wrote this book." Jackson also warned that the result would not be pretty, since Zocchi was advising self-publishers how to save money. "It tells you how to do a cheap-looking job without spending every cent you own." Despite this, Jackson concluded, "On the whole, I recommend this book highly. I wish I'd seen it a year ago. If you ever intend to see a design professionally, order this one."[8]
