Place this "worm" on the 100 square and find the total of the four
squares it covers. Keeping its head in the same place, what other
totals can you make?
There are six numbers written in five different scripts. Can you sort out which is which?
Put operations signs between the numbers 3 4 5 6 to make the highest possible number and lowest possible number.
Can you draw a continuous line through $16$ numbers on this grid so that the total of the numbers you pass through is as high as possible?
You may start and finish where you like, and go horizontally, vertically or diagonally but you may only pass through a number once and the line must not cross itself at any point.
If you repeat this but only go horizontally and vertically and never go diagonally, what is the highest score then?
