Description of App

Play chess, watch games, or chat on either FICS, Free Internet Chess Server or ICC, the Internet Chess Club. If no account just click the connect as guest button and get started playing.

The Diamond Chess board features engine analysis with one click when observing a chess game or examining one. Diamond also has a load PGN option and logs all played games to PGN. Multiple games can be up at once and users click the next or previous buttons to move between them.

We support both chess and the server's variants such as Crazyhouse, Losers, Atomic Chess, Giveaway or Suicide Chess.

Diamond has an accessible board to use with Voice Over for the visually impaired. With voice over on, if a user taps a square it will speak its contents such as "e4 empty" or "e4 white pawn" and there is a speak move with Voice Over on.

Join channels and chat in the Diamond console or if the users is familiar with them issue server commands. For ease of chatting on channels which are numbers like channel 50, a send prefix button can be used to set up the prefix "tell 50" if that's the channel selected so the user need only type their chat line with no command to send it to the right channel.

ICC is a paid server with a one month trial and free guest access. FICS is entirely free.
