From the makers of Lume comes Lumino City, a beautifully designed puzzler, with an i0S 9 extra feature. For those curious about how it was built (a three-year project), a free app, The Making of Lumino City, explains. Lumino City (State of Play Games, iOS, $4.99; also Mac and Windows versions; Gr 2 Up) combines the best of handmade artistry with technology to create a breathtaking app experience. A young girl, Lumi, must undertake an adventure to find her kidnapped grandfather, the caretaker of eponymous city. Armed with a backpack to collect useful objects and a handy manual, she ventures forth through the city’s various locales toward her goal. Each new site offers the opportunity for users to consult the all-important manual, solve puzzles, and work their way to the next location. The captivating adventure begins at the Gatehouse, where appsters help the girl use lemons to create electricity. In total, there are 14 sites to visit, each with an incredible variety of puzzles to be solved. Viewers must consider, experiment, and interpret the manual in order to help Lumi advance through the different locations or levels. This BAFTA award-winning app's intricate world was painstakingly created from paper, cardboard, metal, and thin sheets of plywood. The designers added wired circuits to create lighting and small motors to produce movement. Both motors and lighting combine with photography, animation, and computer code to create the app's interactive elements. There are no in-app purchases, and new with iOS 9, users may film their app experience to share with others. Those who enjoy musical background, while playing games will find the production’s soundtrack pleasing. Thought-provoking, aesthetically pleasing, and intellectually challenging. The app is available in a number of languages. A trailer is available.—Cindy Wall, Southington Public Library, CT
