      pretty good! But I would have thought, that:

      • It has exactly four factors.
      means, that it has four factors except 1 and the # itself, as otherwise there wouldn't be a unique solution.

      So, any other suggestions?

        As no-one's answered, i'll just say that you take the number of letters in each number and multiply:

        Seventeen - 9
        Twelve - 6

        9*6 = 54

          I think it could be 92 or 98 as they both reply to all conditions I think

          • Right, 74, 92, 98 are the three numbers left excluding the factorization statement. (so probably 74 was the answer)
            So, we can close this round as well.

            anyone else for the next one?

              a quick one:

              Shaun Murphy* weighs 100 kg plus half of his actual weight.
              How much does he weigh?

                          Who? It's all fictitious, remember. Now, if I had written Stephen Lee....

                          • sorry berolina, I just thought it would be better to post my answer invisible, in case somebody else is answering too, so I don't spoil the fun too early (since we don't have points for answers anymore but rather having fun solving the problems)

                            • Having had such good fun playing snooker with the menagerie of Davis_greatest's pets, I decided to go along to my local zoo and see what other animals could challenge me to a game.

                              After a disastrous attempt with an elephant where, while leaning over to reach a long shot, his tie touched a red and he got angry when I called a foul, causing him to smash the table to pieces, I took up the offer of a game against a giraffe.

                              Giraffe rules are different to standard snooker in a number of ways. For a start, they are not very good at snooker, and have pockets the size of dustbins.

                              There are the same colours involved on the table (red, yellow, green, brown, blue, pink, black) however they are differently valued from a normal game of snooker.

                              Instead of a triangle of reds, there is a pyramid, where the back row has 6 reds, and the very top of the pyramid is a single red ball.

                              All balls are valued differently as well. The seven different colours have prime number values starting with the lowest prime number for the reds and moving up the chain of prime numbers thereafter.

                              In addition, there are more than one of each coloured ball on the table (when clearing the colours, all yellows are potted first, followed by all greens, etc). The value of the ball determines how many of that colour are present on the table (e.g. if the yellow was worth 99 points, there would be 99 yellows on the table).

                              Anyway, my giraffe friend broke off in the first frame and I, being on top form after my games against the gorilla, scored a maximum break in the first frame.

                              What was that break?

                              • Not completely clear on the shape of the pyramid of reds, to be honest. Assuming its a triangular-based pyramid, with layers of 1,3,6,10,15 and 21, then there are 46 reds worth 2 points each, potted with 46 blacks worth 17 points each, and a colours clearance of 666 for a maximum break of:

                                1540.
