Stampede DesignKuku Kube is a simple looking but insanely challenging color quiz that tests your eyes ability to differentiate shades of color. The game starts out easy with a puzzle containing four huge squares with an odd shade that is easy to spot. As the 1-minute timer ticks and the player progresses, the squares increase in numbers and the odd shades become less obvious that makes you want to max out your screen contrast and brightness. You also probably need to play a couple of rounds to score better. At first try I managed to score a measly 17. My final score was 26. Hit the button below to test your eyes accuracy. You can also try it out on mobile devices.
I saw a huge numbers of Kuku Kube games on the play store, some of them are really good, others good but full of ads. I also found one which looks nice, it is simple and has no ads. This is the link: https://play.google.com/store/apps/details?id=com.imjk.unique. Another good point is that has online leaderboard integrated, I managed to do 67 on time race mode and 101 on the other game mode. Still trying :)
