u.4. How can I compose (and save) my own convention card?
Start by selecting the convention card environment. Now select a predefined convention card
that best matches your requirements to be the base convention card for NS. Choose 'Edit'.
Now select 'Create a new convention card' and enter a new name for your convention card. You will subsequently walk through all the
convention card screens, where you can change anything you like. In the final step the
new convention card will be saved. You can now select the new convention card for both NS and EW.
u.5. I want to remove certain users. Is this possible?
Yes, go to [Settings\Username].
u.6. Is it possible to replay a deal?
Select [Actions\Replay deal].
u.7. When replaying a deal in a tournament the results are not kept. Bug?
No, when playing in the tournament environment only the very first results will be saved.
To be able to also store new results you should remove the existing results first; in the
tournament environment: [File\Tournaments] select [File\Delete results].
u.8. Can a random deal be played again in another session?
Every deal has a unique number. You can replay a range of random deals, for example using
different thinking time settings for Jack or using different convention cards. Another method
for replaying deals is to store them separately, to be played again later on.
u.9. How can I remove convention cards I created?
Enter the convention card environment and select the convention card.
Now use the 'Delete' button.
u.10. How do I print the complete internal manual?
The manual is available as a pdf and can be printed.
u.11. Does Jack play in a network?
Yes, Jack can play both on a LAN or on the internet.
u.12. Where can I find the vulnerability?
Vulnerability is indicated by the highlighted direction indicators (i.e. colored red)
both in the auction and on the table. Red means vulnerable. You can also change the settings to
have vulnerability stand out even more.
u.13. Is it possible for me to obtain the Dutch playing cards on the screen?
Standard Dutch playing cards are on the CD but can also be obtained
using [Help\Search for updates].
In the Dutch playing cards collection the aces feature some historical
Dutch buildings, it might be fun to have a look at them.
After installation you can use [Settings\Table] to select the
Dutch playing cards.
u.14. Network play over the internet does not work. Why not?
Possible causes are:
1. The Server computer has a firewall. The Server computer must allow the Client computer access
for Jack to be able to establish the connection. How to do this depends on the firewall software.
2. Jack says that he cannot establish a connection. Normally this indicates that the Client
computer can not find the Server computer because the internet connection is not there.
To check whether this is the case you can use the PING command. On the Client computer, open a DOS window
and enter:
PING <ip-address>
(substituting <ip-address> with the ip-address of the server)
if the number of packages received is 0 than you have a network problem which is unrelated to Jack.
u.15. During tournament play I cannot find the contracts played by the other pairs. Where are they?
In some Jack tournaments only a frequency chart is available and not the contracts played by the other pairs.
The reason is simple: the organisation of those tournaments did not enter the contracts played
and we did not get that data.
u.17. When will a new version be released? Should I wait for it?
It is not necessary to wait for a new version to be released. Jack is still
ahead both in playing strength and user possibilities but yet is also still
constantly being improved.
Registrer your purchase, if shortly after your
purchase a new version is released you will receive a suitable offer for
an update.
The Jack team does not release a new major version every year. In between major versions we sometimes have so much to offer a new minor version is released (a new number behind the decimal point, for example 6.11 for version 6). If you are in possession of its major version you can download and install the minor version for free. From within Jack 6 you can use [Help\Search for updates], to contact the JackBridge website and install the updates.
Several new components and improvements were offered this way since the first release of Jack 6. This is an ongoing process enabling you to always have the most recent Jack 6 at your disposal.

If online activation keeps failing you should select manual activation. On screen an identification code, consisting of 16 strings of 4 characters, is displayed. Submit this identification code together with your registration code to us and you will receive the autorisationcode.
i.8. The "update code" box on my booklet is empty, can you get me an update code?
You don't need an update code, the box is intentionally left blank.
If you bought Jack as an update, you can use the empty box to note
your previous version registration code.
Both when installing Jack 5 or the update from 4 to 5 the program will
prompt you for your registration code. Here you should enter your new
Jack 5 code. If your version is not the full version but the update from
Jack 4 to 5 the program will subsequently prompt you to enter your Jack 4 code.
i.9. Can I install the Jack 6 update on computers without Jack 5 being present?
The Jack 6 update can, just like the full Jack 6 version be used on new computers without the
presence of Jack 5. You do need the Jack 5 registration code during the installation.
i.10 Does Jack install on an iPad or tablet?
Tablets, like the iPad, usually operate using a different operating system
(iOS or Android) and do not comply with the system requirements.
The only exception are tablets that run Windows 8 and are equipped with an
Intel X86 compatible CPU. Windows 8 tablets that are equipped with
ARM processor do not meet the system requirements.
For more information please contact your tablet supplier.
