Build with wooden blocks, anywhere and without the need to clean up afterwards. Experience your child building a tower of colorful wooden blocks and then push at the blocks to knock it over, with the block scattering around on the floor. No need to clean up, but there is a chance of high squeals of joy when the RC car crash into a tower of cows and pigs. Your child can also learn numbers with audible number blocks, bounce or throw the balls, drive the train, or play Tic-Tac-Toe or Four in a row in 2 or 3 dimensions. In addition it’s possible for your child to store their own constructions for later use or play with one of the many preloaded constructions. There is no points or levels to complete. This is a game of creativity and freeform play.
