Don't laugh! In general, I do not like games mainly because I do not play. I do not PLAY chess for instance.........I am serious! If I cannot learn from it nor force my brain to stretch out, I deem it as a useless endeavor and go about my way. On a referral I tried out this Apple App because I was told it is good exercise for the brain. It's not just good, it's fantastic! Granted, it would seem simple for it is nothing more than a match three, but there are so many twists and turns throughout the entire process that there is no way a person can find a common pattern , as it were, from one game to the next nor even in a replay. If a person is as worried about perfection as I, it is indeed a hazardous journey but I have found in the past that losing does have it's perks in that some things like Cubis Creatures is an overwhelming reminder that losing is a part of learning.
