Are you ready to watch your child kick their learning into high-gear? Crazy Gears is a new-aged digital puzzle game, designed with a real mechanical engine and with children's critical thinking skills in mind! Hours of fun guaranteed for everyone who is up for the challenge, yes, even you Mom & Dad! *** Children's Technology Review Awards 2015 *** *** Parent's Choice Gold Winner Fall 2015*** *** App of the week by Fun2Tap *** *** Best of the Best by Best Apps For Kids *** *** Featured worldwide by App Store as a Best New App *** ABOUT CRAZY GEARS Explore a captivating digital playground in this tantalizing puzzle game! Children manipulate gears, chains, rods, and pulleys, to pull themselves through each level, which teaches them how different mechanisms affect one another when constructing a machine. Each reasoning challenge was carefully designed to adhere to the theories of educational technology pioneer, mathematician, computer scientist, and designer of the first programming language for children, Seymour Papert. “The best use of games is to leverage their tendency to enhance learning”- Papert Recommended Ages 5-9 As a child, Papert fell in love with gears. Their movement fascinated him in every way and inspired his career. Crazy Gears was conceived not only as a tribute to him, but with the hope of providing a child with the inspiration to discover and understand the physical properties of mechanisms found in their everyday lives. Such complex notions include tension, motion, and gravity. We achieve this by encouraging the child to manipulate the objects in each level to determine how they work together to accomplish a goal. Interactions with technology give kids the power to construct their understanding of STEM/STEAM subjects in meaningful ways. Here we engage them in play that does just that!

*** Featured as "App of the Day" on the App Store! *** Thinkrolls Space is a child-friendly puzzle game that’s out of this world. Colorful heroes boldly roll where no Thinkroll has rolled before, in over 200 mazes set across seven unique planets. A cast of oddball aliens will make you grin from ear to ear. But you’ll need brains and nimble fingers to reach your goal—and catch the waiting UFO that will beam your Thinkroll to the next fun-filled planet. CLOSE ENCOUNTERS Thinkrolls and Thinkrolls 2 introduced our revolving heroes. Thinkrolls: Kings & Queens added exciting new concepts—and dragons. Now Thinkrolls Space blasts the award-winning series into outer space. You’ll meet goo monsters, bleeping robots, spring-like soprano aliens, and cheese monsters who love munching moon cheese. You’ll face vanishing rainbow bridges, plasma fields, teleporters—and more. Each of these can help or hinder. You must figure out which—and how to move and match objects to clear a path, get the key, and open a gate to the next level. REACH FOR THE STARS Two difficulty modes and unlimited penalty-free retries ensure the 200+ level journey is stress-free for children and adults alike.
