SwissSys tournament software is available for Windows95 and later Windows platforms. (Sorry -- no version for Windows 3.x or for the Mac, although SwissSys does work with Windows emulation software for the Mac.)
1) Who would want to use SwissSys?
Almost anyone who directs chess tournaments. No size is too small, and sections up to 1000 players are child's play to pair. Regular Swiss tournaments, team and scholastic tournaments, round robins, ladders, and double-blitz tournaments are all easy to manage.
2) What does it do?
It makes pairings for Swiss system (and round robin) tournaments, following all USCF (or FIDE) rules for alternation of color, transposition of players--the whole business. It lets you print out pairings, standings, wall charts, upset results, new ratings, and lots more. In fact, there isn't much it can't do for you except make the coffee. It can import player registration information from the USCF supplement on diskette with just a few keystrokes. It is extremely flexible and customizeable, making it the ideal assistant TD for all levels of competition.
3) Where has it been used?
The U.S. Open, the National Open, the World Open, the Mexican Open, and thousands of club and regional tournaments from Queens, New York, to Queensland, Australia.
4) Can it save money as well as time and aggravation?
Yes! Using SwissSys you can generate ratings report files which the USCF can read from the files you upload to them, saving you 50% on your ratings fees. It doesn't take many tournaments for SwissSys to pay for itself using this feature!
