Play Popword by click-and-dragging across adjacent letters in the grid and releasing the mouse button when you have selected a word.

Each successive selected letter must be directly next to the previously selected letter (either horizontally, vertically or diagonally).

If the word you have selected is a valid English word, the letters will 'pop' away and the letters above them will fall to take their place.

The maximum length of a word is 8 letters.

As you play the game, more letters will fall from the top of the screen - the aim of the game is to prevent the grid from overflowing by popping words.
