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 :)
