Children play in groups of two, with one stethoscope that they can use to listen to the sounds in the blocks. At the left ‘machine‘ in the factory they can change the letters inside the blocks, by turning the wheels. When they hear the sound they need, they write the corresponding letter on the touchscreen and then the sound is loaded into the block. The right ‘machine‘ is for loading a string of sound blocks into a white word block. By pressing the big button the word jumps from the green blocks into the white. The word can now be printed in the chimney - a sticker will pop out from the top.
