A deck system employing a plurality of specially configured floor boards which can be coupled to the joists of the deck via a plurality of substantially hidden fasteners. Each board includes similarly configured opposite sides that define a longitudinal groove therein. Each hidden fastener is rigidly coupled to a respective joist and positioned between a pair of adjacent floor boards. Each fastener forms a mating relationship with the sides of the boards to thereby rigidly couple the boards to the joists.
