SwissSys Software

Whether you are a newcomer to tournament chess who has been drafted to direct an elementary school championship, or an experienced TD who is looking for software to make everything run smoothly at a high-stakes event, SwissSys is up to the job.

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, certificates, 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 member databases published by the USCF, the CFC, FIDE, or your own custom player lists.

SwissSys is extremely flexible and customizeable, making it the ideal assistant TD for all levels of competition. On top of that, our customer service is unbeatable.

Download a free, no-hassle, no-ad trial version and see for yourself, or check out the video tutorials *here*. 
Although there is no version specifically for the Mac, SwissSys runs great on the Mac if you have Windows emulation software installed, such as Parallels, or Apple's free BootCamp.
