Before getting started, let's explain a few rules to help you achieve maximum fun!
Each day, a new puzzle is generated consisting of 20 letters and a unique placement of modifier tiles on the game board (everyone who plays for the day sees the same puzzle). The main objective is to maximize your score by creating a crossword from the given letters, and to rise to the top of the leaderboard. Do so by dragging tiles from the bottom of the screen onto the game board.
A valid solution must always have a letter placed on the green start position in the top-left. The purposes of the colored modifier-tiles are explained in the 'Tile Legend' on the right side of the screen, but there are other conditions which may affect your score:
Usually the best score requires matching some of these conditions (but not all may be possible at once). When you're happy with your solution, click 'Submit' to post it to the leaderboard. After submission, you may try again and submit a new solution if you beat your previous score, but you will not be able to see the solutions of other players until the next day. Now, get going and come up with a truly clever solution!
