If you cant play chess then draughts is a good place to start. You may have a programme already on your computer or tablet, but if not here is a link to an online game to test your skills.
Ok, so you managed to beat the computer at draughts? Well done.. Now have a crack at beating it at chess. This might be a bit trickier, but stick with it and learn from your mistakes. If you can beat it, you are showing great skills at planning and logic.
