Fun for kids and adults alike and plenty of challenges at all levels. *Dinosaur Chess by Mls968 This is a great program. The lessons are interesting, and play levels go from easy to difficult. My 4 and 6 year olds are learning the game, and it's helping novice players like my wife and I too. Highly recommended to anyone who wants to introduce their children to chess! *An excellent app by Adg6 A wonderful app. Ideal for anyone new to chess. It is even fun for experienced chess players. *Highly Recommended - by doled "This is a fantastic chess teaching game. This game alone makes it worth buying an iPad. My three year old now knows the piece names and basic moves. My six year old is well on her way to playing a full game. Our family has had an iPad since the day the iPad was released and this is one of the best apps we have." *Great! - by TonySchleizer "This game has gotten my 5 year old interested in chess. Great tutorials that get progressively harder as skills improve." * Great for getting started - by Milfordthelargebonedgorilla "This has been fantastic for my five year old son...using this in addition to a real board and pieces has helped him immensely in understanding each of the pieces, how they move, their strengths and weaknesses...a terrific way to introduce young ones to the game without overwhelming them" * Great learning tool - by Triplescoop "I have an adopted 7 year old boy with fetal alcohol syndrome. It is very hard for him to learn to play games. Checkers was very hard for him to learn. I thought that chess would be something that he would have to wait to learn. I bought this app even though there were no reviews. So glad I did! What a great teaching tool! I love the mini games that teach the directions that each piece can move. We play slowly but my son can play chess! I recommend this for anyone who wants to learn the basics of the game. This app is for beginners. Great for kids! Thank you to the developers of this app!" *Super! - by Chess player "Hats off to the developers. A fun program for kids." *Ideal For kids - by Kingkot "This game is ideal to teach the kids in the chess."
