About board

In duplicate bridge, a board is an item of equipment that holds one deal, or one deck of 52 cards distributed in four hands of 13 cards each. The design permits the entire deal of four hands to be passed, carried or stacked securely with the cards hidden from view in four pockets. This is required for in-person duplicate bridge tournaments, where the same deal is played several times and so the composition of each hand must be preserved during and after each play of each deal. When bridge is played online, the functions of the physical boards are replaced by the software.
