The simplest way to score duplicate bridge. Duplicate Pairs, Teams of 4, Swiss Pairs, Swiss Teams and Individuals. Used in over 3000 clubs in 63 countries 200+ movements Supports wireless scoring systems.

The BridgePad™ scoring system, developed by a lifelong Duplicate Bridge player, is a sophisticated, yet easy to use Contract Bridge Scoring System for eliminating the distracting and time-consuming tasks of the traditional paper-based scoring system. Paper recording and manual entry of results into the scoring program is completely eliminated along with scoring errors and disputes due to mis-readings. Using the BridgePad™ system, the typical long wait for the final results of a game is dramatically reduced - final results are published almost immediately following the completion of the final board.

The BridgePad™ system frees everybody to concentrate on Bridge.

• Instant Scoring and Comparison
  • Board scores are calculated instantly and sent to ACBL's scoring program
  • The BridgePad™ system informs players about correct table, board number and vulnerability, avoiding errors and conflicts.
  • Final game results are calculated immediately and disseminated to the players without delay.
• Smoother, Faster Games
• The game Director can supervise the tournament without the distractions of collecting round score sheets and mediating scoring disputes.
• One game Director can supervise more tables and more sections with less effort.
• Players ACBL numbers can be entered by players at the tables and instantly sent to the ACBL scoring program.

What is the BridgePad™ system?

The BridgePad™ wireless scoring system consists of

• A *compact battery-powered wireless BridgePad™ Terminal at each playing table. Players enter their contract and board results into the terminal after each round.
• A BridgePad™ Base Station connected to a computer that receives scores from the BridgePad™ terminals via wireless transmission and instantly transfers them to ACBLscore, or other standard scoring program.
• BridgePad™ Software that connects the BridgePad™ base station to the ACBL scoring program .
• The BridgePad™ terminals can not only send information to ACBLscore, but also receive information to be displayed to the players at the tables. Movement information from the scoring program is used to determine which pairs and which boards are at a specific table at each round of the game.
• The BridgePad™ terminals can receive and display a comparison of results for the board just played against results obtained by previous teams playing the same board, and they receive and display the final results of the game.

*actual size approximately 6' X 3' X 3/4'

SC 2.1 - The Number of Match Points per Table

Results are scored by allocating match points to each score for each board.
The more pairs compete for each board the higher the match points to be divided.
The lowest point score receive nil points, the second lowest 2 points, the score above that 4 points, and so on.

A set number of match points per board are divided between the NS and EW pair on each table.
The total match points per board to be divided on each table depends on the number of pairs playing that board.

Number of Tables	Match Points per Table
2 3 4 5 6 7 8 10 etc.	2 4 6 8 10 12 14 16 etc.

Above listing assumes that each board is played on all tables.
If at the end of the play session some boards were not played on all tables then the match points for that board are also less.
For example if a board was only played on 3 of the 4 tables in play then only 4 match points (MPs) per table are allocated for that board.

SC 2.2 - A Simple Match Point score

EXAMPLE 1 = 4 Tables : 6 match points per board
6 points are divided amongst the 2 pairs on each table.

BOARD 1

Contract	by	Tricks made	NS score	EW score	NS MPs	EW MPs
3 NT	NS pair 1	9	+400	(-400)	4	2
3 NT	NS pair 2	10	+430	(-430)	6	0
2 NT	NS pair 3	10	+150	(-150)	2	4
3 NT	NS pair 4	8	(-50)	+50	0	6

Be aware that a positive score for one side is at the same time a negative score for the opposition.
A score of 400 for NS is a score of minus 400 for EW. The negative scores are not recorded on the score sheet.

SC 2.3 - Averaging Match points

When 2 or more tables have the same score their combined match points are averaged and equally divided amongst the tied pairs.
For example on Board 2 below :
EW pair 2 and EW pair 3 have a shared 'top'. They share equally their combined match points of 6 + 4 = 10 points, and each pair receives 5 match points.

BOARD 2

Contract	by	Tricks made	NS score	EW score	NS MPs	EW MPs
2 Spades	EW pair 1	8	-	110	6	0
2 Spades	EW pair 2	9	-	140	1	5
2 Spades	EW pair 3	9	-	140	1	5
1 NT	EW pair 4	8	-	120	4	2

On Board 3 below an example where three pairs with the same point score equally share the match points.BOARD 3

Contract	by	Tricks made	NS score	EW score	NS MPs	EW MPs
1 NT	EW pair 1	6	50	-	6	0
2 Clubs	EW pair 2	8	-	90	2	4
2 Clubs	EW pair 3	8	-	90	2	4
2 Clubs	EW pair 2	8	-	90	2	4

When a hand is Passed in (no bid other than 'Pass' was made) each side scores nil trick- and bonus- points, but still share in the Match points as shown in Board 4 below.BOARD 4

Contract	by	Tricks made	NS score	EW score	NS MPs	EW MPs
1 NT	NS pair 1	7	90	-	6	0
Passed In	NS & EW pairs 2	-	0	0	4	2
1 NT	NS pair 3	6	-	50	1	5
1 NT	NS pair 4	6	-	50	1	5

SC 2.4 - Match pointing an 'Average score'

When on a table the play of a Board is not completed within the allocated time (in a tournament) or some irregularity occurred which made play of the board invalid the Director of the competition may assign to that table an Average score.

The procedure in such a case is as follows :

1. Both NS and EW on the table in question receive an 'Average score', which is half the number of match points of the normal total.
   (For 4 tables half of 6 MPs = 3 MPs)
   
2. The other tables are Match pointed assuming their was one table less in play.
   (4 - 1 = 3 tables ---> 4 MPs per table)
   
3. in addition all pairs on the unaffected tables are given 1 extra MP.

An example is shown on Board 5 below, where the pairs NS4 and EW4 have received an 'Average score'.
BOARD 5

Contract	by	Tricks made	NS score	EW score	NS MPs	EW MPs
3 NT	NS pair 1	9	400	-	2 + 1 = 3	2 + 1 = 3
4 Spades	NS pair 2	10	420	4 + 1 = 5	0 + 1 = 1
4 Spades	NS pair 3	9	-	50	0 + 1 = 1	4 + 1 = 5
Ave.	NS & EW pair 4	-	-	-	3	3

SC 2.5 - Calculating Percentages

The percentage score is the actual match point total a pair wins divided by the maximum total theoretical possible (= 100%).
For example for a 4 Table movement playing 18 boards the theoretical maximum score is :

6 (MPs per table) x 18 (boards) = 108 MPs =100%
For example assume that the NS players had the following match point totals during a play session.

NS1 = 58 points ----> percentage = 58/108 = 53.70 %
NS2 = 64 points ----> percentage = 64/108 = 59.26 %
NS3 = 40 points ----> percentage = 40/108 = 37.04 %
NS4 = 54 points ----> percentage = 54/108 = 50.00 %

Percentages above 50% are above averagescores
Percentages below 50% are below average

Duplicate Scoring Programs In C

scores

The total number of MPs distributed over a session is :

MPs per table x Number of Boards played x Number of Tables (= 4 x 100%)

Each side receives half of this (2 x 100%). Therefore the MP total of all NS pairs (likewise for all EW pairs) should be 216 MPs.
Above example adds up correctly to that amount. This is always used to check that all MPs were calculated and added up correctly.

SC 2.6 - Calculating Handicaps

Pairs or individual players can be given a handicap according to their average percentage score over a period of time, by bringing their average up or down to 50%.

Example 1

A player who received these percentage scores over 5 weeks :
49.05% + 44.77% + 51.02% + 46.45% + 40.82% = total 232.11%
has an average score of 46.42%
His handicap is therefore 50.00 - 46.42 = + 3.58
His/her handicap result = actual percentage score + 3.58 (handicap)

If his next result is 48.40% then his handicapped result will be 48.40 + 3.58 = 51.98%

Example 2

A player who received these percentage scores over 5 weeks :
55.04% + 51.63% + 47.97% + 59.32% + 57.48% = total 271.44%
has an average score of 54.29%
His handicap is therefore 50.00 - 54.29 = - 4.29
His handicap result = actual percentage score - 4.29 (handicap)

If his next result is 53.70% then his handicapped result will be 53.70 - 4.29 = 49.41%

A player can be given a handicap after playing at least 5 times in a club.

Duplicate Bridge Scoring Computer Programs

The handicap is usually recalculated after 10 weeks, leaving out the worst and the best result and averaging the remaining 8 scores.
Handicaps should be reviewed regularly, always taking the last 10 results.
It is best to give each player an individual handicap (even if playing consistently with the same partner).
This handicap can be used when playing occasionally with someone else.
Handicap for a pair should be the average handicap between the two.

Player 1 = -3.58 Player 2 = + 4.29 Pair handicap = +0.35

SC 2.7 - Score sheet Example

How Does Duplicate Bridge Scoring Work

Here is a sample traveling Score sheet (called 'traveler') on which all scores and Match Point allocations can be calculated.

On the example below the players compete in an individual movement where each player has his own number and plays during the course of the session with several different partners.

Depending on the resolution setting of your computer monitor you may need to enlarge or reduce the printout of the 'traveler'.
