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.

What our experts think

Boys and girls alike absolutely loved solving the Crazy Gears puzzles! They were keen to reach the next level, and you could see the gears grinding in their own heads as they worked to figure out solutions. As they progressed through the game, the increasingly difficult levels meant that the children continued to be challenged, and were able to build on their knowledge at each stage (for example, learning to connect a rotating gear to a stationary gear, in order to make the second one turn).

It was great seeing children practice their problem solving skills by experimenting with the wheels, chains, gears, and pulleys, to work out the puzzles. This also helps give children an understanding of how these mechanisms work, which are useful principles in Science and technology. We were equally delighted to see how much this appealed to both boys and girls.
