Strategy used: Guess and check
For question 23, I had to choose which number from 1-6 that with repeated rolls of a dice would get me from S to F in the least amount of rolls. Between S and F there’s 20 numbers but it is a game of snakes and ladders so you had to take this into account.
I realised that the number had to be even as there was only one snake on an even number.
I thought that 6 was the correct answer but I realised that it landed on a snake which took you back to number 1 so needed more rolls than other numbers. Then I tried 4 becuase thats a second even number but that also landed on the only snake on an even number. So I tried 2 and found that it dodged all the snakes, and used 2 ladders so it only needed 5 rolls. This was the lowest number of rolls compared to the other numbers.
