First, I am conducting a very short survey into sleep as part of the Edinburgh International Science Festival and would love you to take part. The link is here. Thank you for that – much appreciated.
OK, to the puzzle. I want to play a game with you. We have three unbiased dice, and each of the two of us have a target number. My target number is 9 and your number is 10. On each round of the game we throw all three dice and add up the numbers. If I get my target number I get 1 point, and if you get your number you get a point. The winner is the person with the most number of points after 20 rounds. There are 6 ways of getting 9 (1,2,6: 1,3, 5: 1,4,4: 2,2,5: 2,3, 4: 3,3,3) and 6 ways of getting 10 (1,3,6: 1,4,5: 2,2,6: 2,3,5: 2,4,4,: 3,3,4) and so it seems to me that it is a fair game. Want to play?
As ever, please do NOT post your answers, but do say if you think you have solved the puzzle and how long it took. Solution on Monday.
