Cards - Both your cards and your opponent's cards are displayed in each game, unless the rule 'Open' is switched off, in which case only your cards are displayed. When it is your turn, you must choose a card from your hand to play by clicking on it on TT.com, or hovering over it on TTX.com. It will then appear on the board, and can be placed in the square of your choice by another click.

Main Board - This is where the game takes place. Once you have chosen your card, click on one of the squares to play the card in that square.

Score (bottom left and right of main board) - Shows how many cards you have in your possession (on right) and how many your opponent has (on left).

Blue information box - Shows information about the game you are currently playing, including the game and trade rules, and the time limit. This is only available in small mode. On TTX, the rules in force are displayed on the top line of the message box.

Message Box - You can write messages to the other player in this box while you are playing the game. Press the 'Send' button to display the message.
