Every tech company has some sort of Easter Eggs built into their products and Facebook Messenger has one too. The Easter Egg in Facebook Messenger lets you play chess with a friend directly in a Facebook chat window.

However, to launch the game and play, you need to input special phrases.

BetaNews shares the instructions:

  1. During a conversation, type @fbchess play and a board will appear. Your friend will go first.
  2. Select a piece using K for king, Q for queen, B for bishop, N for knight, R for rook, or P for pawn.
  3. Then add the letter and number representing the space you want to move it on the board.

So, for example, you’d type @fbchess Pd4 to move it to that space. If more than one piece can go there, you’ll be asked which one to move.

If you want a larger view of the chess board, click on the chat menu settings icon and select “See Full Conversation.”

Sounds a little complicated. Maybe you should stick to the full fledged chess games available online. However if you like easter eggs or would like to surprise your Facebook friend who doesnt know about this Easter Egg, now’s your chance.
