Those who are familiar with it will tell you that Ludo, like human life itself, is a game both of chance and skill. You need skill in deciding how to make the most advantageous use of the figures that turn up on the die when you cast it. Since each player has at least four alternative ways of using his figures, two players with equal luck may fare differently, depending on how cleverly each one uses his figures. The element of luck, again as in human life, plays a dominant role however. For no matter how skilful a player may be in using the figures he gets on the die, he has a slim chance of winning if he continually throws low figures. While a combination of ones and twos may be useful in checking the advance of one’s opponents, it will not take one home fast enough to win. On the other hand: consistent throws of sixes and fives with the very minimum of skill, will help a player to home all his four counters before any of the three other players, unless, of course, he has no idea of the game at all.
It is implied in the passage, that in Ludo threes and fours are
  Dear John,
Many thanks for your letter. I was glad to hear that you had done so well in your examinations. Let me send you my hearty congratulations. You certainly deserved this result as I know you worked very hard. You ask how I have been spending the time since I took my examinations. I have been waiting so eagerly for the result that, I must admit, I have not done half of the things I planned to do during this extended holiday. However, I have been doing a lot of reading. There were so many different things I was interested in when I was at school and did not have the time to read about because they were not on the syllabus. I have read two books about geology, which is a fascinating subject. I hope to make a hobby of geology when I get to the University. It will make a change from the study of law. i have also read several novels mostly modern ones by authors like Graham Greene, C.S Foster and Somerset Maugham. How enjoyable it is to read a book for pleasure and not for examination! I have not given a thought to law, and not read one book about the subject. I shall have e four long years at the University to devote to it.
I have also been going once or twice a week to the National Boy’s Club. I took part in the table-tennis tournament, but I did not do very well, I’m afraid. I have been playing football for the Club every Sunday afternoon. I will certainly let you know my examination results as soon as I have them. I must say that I become less confident about the result each day. It was encouraging to hear that this was the case with you, and since you did so well perhaps there is still hope for me!
Yours sincerely
Osman.
