My mom told me that she can see the chess board and the backgammon board but when it comes to Uno it's just texst. She reads blue 3 but no visual. How can I make her (and my other friends) to see the cards?

Hello,
that's unfortunately not possible at the moment, as it's quite hard to design when a blind developer is working on the Playroom alone.

As you rightly noticed, you can see the board in board games such as Chess, Connect 4 or Backgammon, but other games are textual.

Hello,

This isn't possible. As I'm alone and blind, I need external help for that kind of thing.

If you can help or know someone who can help to improve graphics, ideally with a little programming and CSS knowledge, please contact me.

Thanx for the explanations :)
at least, at the web client, after pressing "layout", Blue 3 becomes blue and red 2 becomes red etc

This is normally also the case on the windows client. There is no graphics, but there are colors.
