We have dozens of games in our house, but this one is a favorite. My 6 year-old son picked up the rules in about 5 minutes, but continues to develop his strategy every time we play. It is simultaneously simple and complex, and a great way to get kids to employ reason and logic, while having fun. This is now one of his two favorite games (the other being Othello, which I also highly recommend). We play it often, and it is a great way to get him away from the TV so we can spend some quality time together. Sometimes I win!
