In the options window, the
following setting can be changed:
The variation. You can choose here which
variation (regular, 'van Eer-Maas' or user-defined) you want to
play.
Animation speed. Here you can set the speed with
which the cards will move over the screen. There are three levels; slow,
medium and fast. This option will have influence during an active game, when
it is changed.
Backside card. The backsides of the cards can be
changed by choosing the one you like the most. 31 for Windows comes with
several backsides. These backsides are bitmap-files and can be changed in any
way you like. It is possible to use bitmap-files that do not have the correct
format, however in that case it can’t be guaranteed that 31 for Windows will
behave properly. This is option has effect on an active game.
Players Names. There are four names included,
which will be used for your opponents. These names can also be
changed.
