Crazy Gears

What it is and what you do with it: a set puzzles using chains, rods, gears, racks, hooks and pulleys.

Combine all necessary items to create a mechanism robust enough to pull the hook and transport the player to the next level.

What we liked: the concept. Excellent set of original puzzles from very easy to quite challenging. Covers many STEM concepts as gears, mechanical systems, motion, ratio, action and reaction and more. Great for building thinking and reasoning skills. 2 play modes (free and timed). Parents' area with detailed progress reports. No ads or other distracting features.

What we didn't like: no hints.
