The playing of the card game of Contract Bridge is still widely played, but at New-Camelot it was found that the game would be more popular with simplified scoring and changes to the bidding system, and so they made modifications, and the modified game is called TigerBridge and is a more popular pastime, sometimes played for fun, but usually as a serious game in the form of a tournament or match where players go in Quest of the elusive Balancing Point. The modifications are as follows:
Terminology was changed to what was thought to be more appropriate:
Suits are known as Houses
Trumps are known as Crests
The Contract is known as The Proclamation
Declarer is known as Proclaimer
Dummy is known as The Lookout
Tricks are known as Rounds
Undertricks are known as Roundsunder
Overtricks are known as Roundsover
Passing during the bidding is known as Declining
The Houses and their rank were changed to what was thought to be more appropriate. The TigerBridge names and ranking for bidding purposes are shown with Contract Bridge equivalents.
|No Crests (lowest rank)||No Trumps (highest rank)|
The Rank of the cards was changed to what was thought to be more appropriate. The TigerBridge ranking is shown with Contract Bridge equivalents.
The Bidding. It was felt that a bid to win a certain number of rounds should mean precisely what is said, and so a bid of seven towers means that the bidder has proclaimed to take seven rounds with towers as crests. The minimum number of rounds that can be bid is five and the maximum number of rounds that can be bid is nine and there is no doubling and so no re-doubling. The total possible number of bids in TigerBridge is therefore twenty-five. The bidding numbers for TigerBridge are shown with Contract Bridge equivalents.
The Scoring was simplified by awarding one point for every roundover to proclaimer’s partnership up to a maximum of five and one point for every roundunder to defenders’ partnership up to a maximum of five. These points are called set points. Upon a partnership reaching a minimum of six set points and leading by two or more set points this forms a set and one game point is credited to them and a new set begun; excess set points are carried forward to the new set except when the game is concluded. The game is concluded when a partnership wins two sets, and if their opponents have not won a set an additional game point is awarded. The game score therefore is either 2-1 or 3-0 to the winning partnership.
The Scoring Table is set out below:
|Set points awarded|
to Proclaimer’s Partnership
|For each roundover|
to a maximum of five
|Set points awarded|
to Defenders’ Partnership
|For each roundunder|
to a maximum of five
|Minimum of six and|
difference of two or greater
(excess carried forward to next
set except when game concludes)
A game is concluded upon a partnership reaching two game points. An additional game point is awarded to the winning partnership if their opponents have no game points.
The remaining rules of TigerBridge generally follow those of Contract Bridge, with one or two exceptions, the main rules are listed below.

A Question of Balance. One of the purposes of the scoring and bidding systems was to bring in the idea of a balancing point in the bidding. This can best be illustrated with an example of TigerBridge where the partnerships are called "AB" and "XY". We will assume all the players know that AB can take ten rounds in lakes and that XY can take four rounds in forests and that this is the most rounds they can win. The bidding could go as follows:
AB bid 5 lakes which gives 5 roundsover and 5 set points to AB
XY bid 5 forests which goes 1 roundunder and gives 1 set point to AB
AB bid 6 lakes which gives 4 roundsover and 4 set points to AB
XY bid 6 forests which goes 2 roundsunder and gives 2 set points to AB
AB bid 7 lakes which gives 3 roundsover and 3 set points to AB
XY bid 7 forests which goes 3 roundsunder and gives 3 set points to AB
We have reached the balancing point of seven rounds where set points awarded have evened out. In some situations the balancing point will be between bids, as would be the case were AB able to take nine rounds and XY six rounds; here the balancing point would be a theoretical seven and a half rounds. If the bidding were to continue in the example, the following would apply:
AB bid 8 lakes which gives 2 roundsover and two set points to AB
XY bid 8 forests which goes 4 roundsunder and gives four set points to AB
AB bid 9 lakes which gives 1 roundover and one set point to AB
XY bid 9 forests which goes 5 roundsunder and gives five set points to AB
As can be seen, both partnerships would want to hold the proclamation below the balancing point, but above the balancing point both partnerships would want their opponents to hold the proclamation. In the above example all the players were assumed to know the whole situation, but in a game of course this would have to be deduced from the bidding, and the balancing point would be a matter of judgement and could change according to the bidding. The bidding could also be subjected to disruptive bids and bluff and counterbluff.
