With over 350 million cubes sold since it hit toy stores in 1974, the Rubik’s Cube is probably one of the world’s most popular toys ever. However, while the iconic cube has an avid fan base, which regularly compete to be the fastest, the brain teaser is daunting for most. It is, therefore, not surprising to hear that even though the toy has been on the market for over 44 years, less than 6 percent of the world’s population is able to solve it. Now, Israel-based startup Particula is introducing GoCube, a hi-tech version of the classic toy that promises to make the puzzle fun and interactive for both beginners and experts.
