Set your tables and get the Howell or Mitchell, guide cards for each table, pair cards and travellers to print, then score the boards here.
Copy each traveller line: the score goes under N-S + or E-W +, whichever side scored. Matchpoints and percentages update as you go and stay on this device.
Scores appear here once two tables have played a board.
In a Mitchell, N-S pairs stay at their table all session. After each round E-W pairs move up one table and the boards move down one. With an even number of tables, E-W pairs skip a table halfway so nobody replays boards.
In a Howell everyone moves and every pair meets every other pair once, so there is one winner. The charts here are complete Howells: each pair plays every board set exactly once. Resting sets sit on a side table between rounds.
Each board's dealer and vulnerability follow the standard 16-board cycle printed on duplicate boards. Scores follow the Laws of Duplicate Bridge scoring table.
A Howell lets every pair meet every other pair and gives one overall winner, which suits 4 to 7 tables. A Mitchell keeps N-S pairs still, is easy to run with 8 or more tables, and gives two winners (one N-S, one E-W).
With 2 or 3 tables you cannot give each table its own boards and still have every pair meet every other pair once and play every board once. The usual fix is to share boards: every table plays the same boards in a round and passes them along. That is what this page gives you.
Tick "One pair short". One pair position becomes a sit-out, and whoever would have played them rests that round. Pairs that sit out play fewer boards, so results are ranked by percentage.
Most club sessions play 24 to 27 boards in about three hours, at roughly 7 to 8 minutes a board. The planner suggests boards per round to land near that; change it to fit your evening.
On each board, a pair gets 1 point for every pair in their direction that they outscored and half a point for each tie. A pair's total is turned into a percentage of the most they could have scored.
A Howell uses more board sets than tables, so some sets rest each round. Put resting boards on a side table; the guide card says which table collects them and when.
