Get ready to challenge your mental agility, focus and concentration with these extreme dot-to-dot challenges. Unlike the games that you remember from childhood, these intricate designs include upwards of 400 numbered points each and use sketching techniques such as line drawing and perspective to create detailed artworks that magically appear 3D when viewed through the enclosed ChromaDepth (R) 3D glasses. Take a break away from screens, multi-tasking, and the hustle and bustle of the modern world and focus your mind on the absorbing task of completing one of these dot-to-dot puzzles. Each dot-to-dot design challenges you to focus your attention on the process of deciphering the numbers in the tangled web. Like the craze for adult colouring, part of the appeal of these puzzles is their focus on a single absorbing task that takes you away from the distractions and stresses of everyday life and forces you to be present in the moment. Unlike colouring-in designs, however, these puzzles require full attention at all times and test your mental agility and problem solving skills. Using 3D imaging techniques each of the 30 designs in this collection jumps to life as you complete the puzzle. The core concept is simple - the specific colour palette used in each dot-to-dot pattern creates a depth that makes your finished animal leap from the page when viewed through the glasses!
