Have you got good judgement? If you think you have, then take the Pinpoint That Number challenge.

The computer will generate a number. To play, you simply drag and drop the arrow to where you think that number is within the range of numbers shown.

You'll get 3 lives for each question. If you get the answer right first time, you get 3 points, but every time you lose a life you lose a point. There are ten questions in each of the three levels, and you need 25 out of 30 to go up a level, so look after those lives!

If you're confused, let Jess show you how to play, then take the Pinpoint challenge!

Good luck!
