Use your knowledge of place value to try to win this game. How will you maximise your score?

Can you go through this maze so that the numbers you pass add to exactly 100?

Choose four different digits from 1-9 and put one in each box so that the resulting four two-digit numbers add to a total of 100.

This challenge combines addition, multiplication, perseverance and even proof.

Can you order the digits from 1-3 to make a number which is divisible by 3 so when the last digit is removed it becomes a 2-figure number divisible by 2, and so on?
