Struggling to find that Grand National horse that catches your eye? Don't know your Last Samurai from your Druids Nephew?

Well worry no more. You can now let the data decide who to take a punt on with our unique gadget.

The gadget takes into account the form of the horses, their jockey's win ratios, as well as weight and odds.

Simply slide the horses on each bar to match the kind of horse you want to back.

Want the top jockey? Then slide the horse on the jockey bar to the right and towards the finishing post. If you want the favourite, then slide the horse on the odds bar to the right.

But choose wisely, you can't slide each of the horses right to the finishing line. The combined distance travelled of all the horses can only be as far as two whole bars.

Good luck!
