I am a play therapist and got this game to help my child clients (6 to 8 years old) who have difficulty with frustration tolerance, impulse control, attention and focus. I put in my playroom yesterday, and my three most difficult children all asked to play with the new toy. This game is fantastic. Children who before this have not been able to tolerate any kind of frustration of their control of a game without a tantrum, a meltdown, or quitting, spent their entire sessions focused on running the ball through the course. When they had difficulty navigating the ball, they tried again and none of the three asked to give up, or play something else. No one completed the course without having to start over, but they enjoyed the game thoroughly, it kept their attention, and although we used it as a 2-player game, they were more focused on besting themselves than on winning against me.
This is an excellent game for teaching children patience, delayed gratification, and the fun there can be not only in winning, but in playing the game. Children will also have the opportunity to build self-esteem, and experience mastery and appropriate control. I highly recommend it.
