Kuku Kube : the game

Kuku Kube is a free browser game to test your eyesight, developed by the network365 Canadian team. This game went viral on internet at the beginning of year 2015.

It is probably based on the Kuku Kube original game, adding to it some levels to increase progressively the difficulty of the game.

According to the game creators, in level 1:

• a score lower than 11 is not a good sign,
• between 15 to 20 you are below the average,
• between 21 to 30 you have a normal eyesight,
• 31 and above: your eyesight is exceptional!

The Kuku Kube game is designed to evaluate the quality of your color vision. However, keep in mind that this is more a game than a medical test, and it will NOT replace a doctor's visit!!

Kuku Kube is also available as mobile applications for Android and iOS.
