I played the game 10 times, and came up with increasingly better resluts. (Scores were 32,29,23,19,21,17,19,17,17,15.) I was stuck at 17 moves, and then watched the animation a few times. After that I was able to get down to 15 moves. I thought this game was fun and I appreciated the feedback, and also the animation. This would be a good teaching tool for K-8 students.
