The Swiss system, handled for you
ChessHost runs every part of a Swiss-system event so the pairings are never your problem.
Automatic Swiss Pairings
Players meet opponents on the same score and never play twice. Each new round is paired the moment results are entered.
Byes Handled
With an odd number of players, the bye is assigned automatically and fairly each round, with no tracking by you.
Tiebreaks & Standings
Scores, tiebreaks, and rankings recalculate after every round, so the standings are always correct.
TV Display
Show pairings and live standings on a TV or projector with one link, in several clean visual themes.
Swiss software anyone can use
Most Swiss chess software is built for arbiters and assumes you know the pairing rules. ChessHost is the opposite. There is no install, no spreadsheet, and no pairing knowledge required. Enter the results and the next Swiss round appears instantly, correct and ready to display or print.
It runs in any browser on a laptop, tablet, or phone, so you can run the whole Swiss event from one device. And because it is free forever with no credit card, you can run a complete Swiss tournament without ever reaching for a payment form.
