On a darts scoreboard, each number is made up by some of the lights in a 5 x 3 grid being lit. The correct appearance of each number is shown below: Darts scores consist of three digits and the score can be anything between 002 and 501. One night, for one player's score, the first of the three digits was faulty and three of the lights were permanently on. All other lights were working normally. The score showed 805.
