Did you know that frogs love climbing ladders? Well they do, and this game proves it!

The computer will randomly choose numbers from a selection of nine. All you have to do is put them in order - lowest at the bottom, highest at the top - by clicking on the rungs of the ladder.

Sounds easy? Well, the computer makes it harder by choosing the numbers one at a time, so you don't know what's coming next. You'll have to do a bit of guesswork, especially with that first number.

It's also against the clock - you've only got a few seconds to place each number, so get a move on! With a bit of skill and a bit of luck, you'll see the frog jump to the top of the ladder.

There are ten questions for each level. When you get 6 or more out of ten, you'll get the chance to move up a level. The numbers will get more difficult as you move through the 3 levels.
