Crossboccia is the reinvention of Bocce Ball by introducing play in 3 dimensions. Crossboccia balls will rest on uneven surfaces. A vertical vector becomes part of the game, so, stairs, tables and chairs can be played upon. Suitable for indoor and outdoor use. So your next arena can be anywhere. This family pack is intended for four players. It contains: 12 playing balls (official contest balls, diameter 3.1", 115 grams), 1 target ball, and playing instructions all in a mesh bag. Cool designs too!
