Hello,
I have found the following bugs relating to Duck Racing:

1. Saving appears to be broken. When attempting to save a duck racing table, a message informs the user that the action is unsupported. This behavior occurs both on the Windows and web client.
2. When using the web client, there appears to be no method to get the descriptions of your cards. You can get such descriptions on Windows by pressing D when hovering over a card.
Thanks.

Hello,
for your second question, are you playing on a touch screen?

If so, you can get a description of a card by performing a long press on the card you want described, with screen readers that would be a double tap and hold.

For the first problem, saving is just currently not implemented for this game, so rather than a bug it's a missing feature.
