I was ignorant when it came to playing darts. ‘It’s just a game,’ I thought. How wrong I was! This material is an excellent read; the games are designed to not only educate but to also build up your confidence and skill levels. I was amazed at how this literature has helped me, especially my mental arithmetic. When you follow the study chart for instance and the check outs, you really start from day one to improve. I thoroughly recommend you buy this book.The concept behind games is inspirational, not just for you but for your opportunity as well. I love the mental and physical challenge this book provides.
