JDB Games was established in 1999 by John D. Barnhart in Albuquerque, New Mexico. Time Vectors, Crystal Draughts, GRYB, and Tholian Go are his games.
Time Vectors was the first game invented for an algebra project in 1969. Originally named Four-Dimensional four-in-a-row, it became popular among a few friends. GRYB was next in 1999. Then Crystal Draughts was designed in 2003.
These games were manufactured and sold from the year 2000 through 2006.
New rules and more games to play have been devised since then.
