Zocchi at his GameScience booth at Gen Con Indy 2007.
Zocchi and his company GameScience 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 is a well-known figure at gaming conventions like Gen Con and Origins Game Fair, where he demonstrates the various inconsistencies in most mass-produced gaming dice.
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. These pictures have not been updated since at least 1995 and do not show contemporary dice. His demonstrations are sales pitches for the unsmoothed dice (often with sharp edges) manufactured by his company, GameScience. Unlike other gaming dice producers, Zocchi guarantees his dice to roll rightly and never to break. However, tests by Jason Mills in 1987 and published in White Dwarf magazine showed that at least one of his dice designs for the Zocchihedron had a significantly uneven number distribution. 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.[clarification needed] Only white dice with black numbers use the older 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 just as uneven.
Due to safety concerns, the 4-sided die (or d4) produced by GameScience has truncated points. After redesigning the die with blunt points, one irate customer[weasel words] sent Mr. Zocchi a long letter complaining that the dice might stop on one of the truncated points.
Mr. Zocchi has invented and produced several "non-standard" dice. These are a 3-sided die, a 5-sided die, a 7-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, with GameScience's characteristic precision-edge unpolished look.
Zocchi has designed a few games himself, including Alien Space, Star Fleet Battle Manual (not to be confused with Star Fleet Battles), The Battle of Britain, Luftwaffe, Flying Tigers, Hardtack, and Battle Wagon Salvo.
