Tempo Game Clock is a multi-player game clock and game record keeper all in one. Use it for custom game shows, tournaments, debates, athletic contests or any situation where a time keeper is required. Create your own game show concept and pilot it at your local theater or club. Turn your theater, club or living room into a spectator game venue, complete with game clocks and scoreboard. You can project the game displays onto a standard digital television or a digital video projector with no special hardware. It is highly customizable to create clock and score behaviors for any game you can dream up. You can create even the most complex time controls and scoring schemes with any number of players. The period lengths can be adjusted to meet tournament rules. Or just place your laptop on a table and enjoy a timed board game with friends. Simply press the space bar to stop one player's clock and start the next player's clock. There are pre-configured games for Chess, Checkers, Go, Boggle, Scrabble and most common Board Games. For chess, the clocks can be operated to compliance with official Clock Rules of the US Chess Federation (USCF) or the World Chess Federation (FIDE).
