Really high-quality construction. Each brick produces a different sound and has different colors and shapes. My son is 9 months old and he likes to hit the bricks together and with other objects. He is occupied for a good amount of time for his age. Anyway, it is a game that children of different ages can play with.

Although it is not the most impressive game of course, for my little girl who likes sounds and is in the phase of hitting small objects together, bells, etc., it is a very nice activity. She discovers sounds, combines the sounds, puts a cube on top, and knocks them down. A very nice game, it keeps her busy enough, it's worth its money. I like that the cubes are wooden, for a change from her plastic toys.
