There are over 65 words related to Christmas (and on the site) for you to work out.
To play the game, enter a word or some letters using a keyboard (either on the screen or a real one) and press enter. It will tell you if the letters are in the word (yellow) and if they're in the correct position (green). The letters on the keyboard also help you to keep track of the letter you've used. Use the rows for more guesses. You have six attempts to find the word.
