Wait.... What? An invisible unknown Piece Style in between in my phone? A glitch?                         Now lemme show you what it shows in my computer...
It shows the name, 'Blindfold'. In the corner preview as you can see above, it doesn't show the pieces... Only board. Maybe it's just a secret for fun, but actually useless. Maybe they mean a fun challenge where the players can't see the pieces... BLINDFOLD CHALLENGE!!!!                                It's just a secret, cuz many people wouldn't find it. Also not many people play chess in their computers, so they'll not see the name too!                                                                                     Thank you for viewing!
