I also do like Cryptokitties actually. I strongly suggest you to try KuCoinplay, its also a gaming platform with easy games. No money required or investment. You just need to exert some time for it to complete the mini-games and tasks there where you will be earning the points and will put you into the rank. The higher points the higher position you have. https://kucoinplay.com/bolt-contest-2-500k/?utm_source=tftj
