The aim of this game is to try to find the number marked between the arrows. To do this, enter 2 numbers one higher and one lower than the number you are trying to find. When you press go, the number line will redraw itself between the values you have entered. Continue until you can see what the number is. When you find the correct number enter it into either of the text fields and press the 'Go' button to finish.
See how few guesses you need to get the correct number.
