No sound for iPad 1, preschooler level – Train Games for Kids: Zoo Railroad Car Puzzles All Review

I downloaded this based on toddler age level (as per the description) but the 9 piece puzzle is too difficult for my 17 mo. grandson. He is still learning the drag/drop function and is not quite coordinated enough for this. He has great fine motor skills, but puzzles require holding down and dragging. There was no simpler game included although the description alluded to one. Also, the sound does not work for our older iPad 1.5.
