This app is from Tozzle. Includes 42 puzzles with a wide range of variety, perfect for all children, highly engaging, especially for autistic kids who have difficulty learning using conventional methods. While Tyler's Dayhab reports in the past 16 months, virtually no change in his ability to learn educational requirements, since giving him the ipad before Thanksgiving, we've seen amazing skills Tyler has clearly acquired. We added this app about a week or so, because Tyler loves puzzles, but tends to eat the wood or cardboard puzzles as soon as we turn out backs, due to Pica. The ipad and the wonderful apps have made a huge difference in Tyle's life.
