Bocce, anyone ?

Bocce is a lawn bowling game from Renaissance Italy.

Modern Bocce sets have eight large balls, in two different colors. The balls of the same color are differentiated by two different patterns of engraved lines, allowing four players with two balls each. A team with red balls, and a team with green balls.

These balls are slightly larger than softballs, but are very hard and quite heavy. Modern balls are made from dense and hard plastic, such as phenolic. In the older days they would have been made from carved and polished stone of differing colors.

As Billiard players bring their own cue-sticks, Bocce players could bring their own Bocce balls.
There is also a small white ball, similar in size to a golf ball. This ball is internally weighted to make it heavy also. Typically it would have an Iron center-weight.
The play of the game is that someone would toss the white ball several yards in a random direction. Then the players would take turns bowling their large balls nearer to the white ball than any of the opponents balls. At the end of a round, the nearest ball would score a point, and all balls of the same color that are nearer to the white ball than the closest ball of the other color, will also score. Then the white ball will be tossed again to start another round.

At the time this game was invented, lodestones (spelled "loadstones" at that time) were laboratory curiosities. The common practice was to have them ground into perfect spheres, and engrave them with latitude and longitude marks aligned to the magnetic poles, to emulate the planet Earth.

Would a Bocce cheater have used his lodestones for Bocce balls, which could attract the white ball, and the player's other lodestone balls, to cheat?
