My DS4 liked mazes pretty early on. I can't remember exactly, but we started getting him maze books around early 3. His love of mazes went away when he started getting better at mazes, and wanted to do harder ones, but his pencil grip got in the way of seeing where he was drawing (still fist grip for him). So, i guess until he decides to change the way he holds his pencil, no more mazes for him! He loved this video game - partial free version here: electric
