SCORING 1
There are many different forms of Bridge:
     Rubber Bridge          Duplicate Pairs
     Chicago                     Team of Four
Though they all have different methods of scoring, the 
basic Trick Score is common to all forms of Bridge. 
A Game is made when the Trick Score is 100 points or more.

TRICK SCORE                           GAME
CLUBS/DIAMONDS 
20 points per trick                   5 Level  5x20 = 100

HEARTS/SPADES 
30 points per trick                   4 Level  4x30 = 120

NO TRUMP 
40 points for first trick then     3 Level  40 + 30 +30 = 100
30 points per trick 
 
OVER TRICKS
Same as Trick Score

BONUSES
Part Score         50 

Game               300 

Small Slam       500 

Grand Slam   1000 

Making a            50 
Doubled Contract 

TOTAL SCORE = TRICK SCORE  + BONUS
In computing Total Score multiply the Trick Score by the bid.
Example:  3 # bid and made 3. 
                                   Trick Score: 3 x 20 = 60
                            plus Part Score bonus:     50
                              Total Score: 60 + 50 = 110

TOTAL SCORE = TRICK SCORE + OVER TRICKS + BONUS
If there are Over Tricks, add  the Over Trick to the Total Score.
Example:  4 !  bid and made 5. 
                                   Trick Score:   5 x30 = 120 
                                            plus Over Trick:    30
                                        plus Game bonus:  300
                     Total Score: 120 + 30 + 300 = 450

TOTAL SCORE = TRICK SCORE + OVER TRICKS + BONUSES
When  computing the Total Score for a Slam (bid and made) add in both the Game bonus and the Slam bonus.
Example:  6 #  bid and made 7. 
                                     Trick Score:   6 x 20 = 120
                                              plus Over Trick:     20
                                           plus Game bonus:  300
                                           plus Slam bonus:    500
                    Total Score:  120 + 300 + 500 = 940

UNDERTRICKS
NOT DOUBLED:    50/ trick (for Defenders)

DOUBLED:      TRICKS SET      POINTS (for Defenders)
                                1                     100 
                                2                     300 
                                3                     500
                                4                     800 
                                5                   1100 
                                6 etc 

When computing Points Scored for setting a contract multiply tricks set by 50.
Example:  5 u bid and set 3.
                   Points Scored:   3 x 50 = 150
If contract is Doubled see above tabel. 
Set 3 (or Down 3) Doubled is 500 Points Scored.
 
MAKING DOUBLED CONTRACTS
When a contract is doubled, and made, the 
Trick Score gets doubled. 
2 u doubled and made: 20 x 2 = 40 Trick Score.
40 x 2 = 80 is the Trick Score doubled. 
Add the Part Score bonus: 50 points.
Plus the Making the Contract bonus: 50 points.
Total Score: 80 + 50 + 50 = 180 points. 
It is possible to double a contract into a game. 
2 $ doubled and made:  30 x 2 = 60 Trick Score. 
60 x 2 = 120 is Trick Score doubled which is game.* 
Add the Game bonus: 300 points.
Plus the Making the Contract bonus: 50 points
Total: 120 + 300 + 50 = 470 points.

* Only if the Trick Score doubled = 100 points or
   more is there a  Game bonus.  Over Tricks are
   added after.  ie 2 # doubled making  5 does not
   get a Game bonus. 
   2 # x = 40 x 2 =80 Trick Score doubled
   30 x 2 = 60  Over Tricks
   60 x 2 =120  Over Tricks doubled
   Add the Part Score bonus: 50 points.
   Plus the Making the Contract bonus: 50 points.
   Total Score: 80 + 120 + 50 + 50 = 300 
   You cannot double a person into a slam.  Slams 
   must be bid and made to get the bonus.
   ie 3 u doubled making 3 gets the Game bonus 
   and Making the Contract bonuses only. 
   Total Score: 120 + 300 + 50 = 470
