Numberwords have a similar grid to crosswords,
but every square carries a number instead of a clue
Each of the numbers 1 to 26, represents a letter A to Z. All occurences of a number represent the same letter
Click on a square (on the actual grid) to select a number
Click on the letter buttons to guess which letter is represented by the selected squares number
There are no penalties for wrong guesses
When you guess correctly, all occurences of the selected square number will be replaced by the letter
When the puzzle is completed, every word (across and down) will be a correctly spelt English word
