I really love this game! I have a brain tumor and a seizure disorder because of it. And on the advice of my doctors,...I’ve been playing Scalak and other puzzle games similar to it as a “precautionary” form of “cognitive, comprehensive and short-term memory loss therapy”. After completing and playing Scalak over and over again,...I’ve been trying to find games as “closely” similar to it as possible. However,...I haven’t been able to find any even “remotely” similar to it! I know Scalak isn’t considered “challenging”,...for most anyway,...but can anyone recommend any other games comparable to it? I’d rather any recommended games’ “difficulty level” be as comparable to Scalak’s as possible. Thank you.

I always wanted a HellRaiser puzzle box & this game is just like building your own.....without all the demons & fleshy bits...UNFORTUNATELY...am I right. Ok anyway. This game is.....Smooth as smooth can smooth Entertaining as...something REALLYentertaining. Sweat & tasty graphics Intuitive movement that you just...get VERY smooth difficulty progression (no “this is to easy” straight to “HOW THE F@?# AM I SUPPOSED TO DO THIS S?#T”) Challenging throughout while still fun and fulfilling Very Relaxing as others have stated Lots of different types of puzzles so not repetitive and MundaneCONS: None, unless you count battery life which is EASILY fixed by tapping HQ on front screen as clearly stated by Devs which rectifies it.WARNING: May forget things like “get clothes out of washer”, “eat food & stuff” & “pick up kid from school” due to complete enthrallment. Not a big deal. Ok, now back to the game...I’m getting withdrawal tremors.!!!WORTH THE VERY SMALL PRICE!!!

I've only just gotten this game and I'm in love. I love puzzles and brain teasers so this was a perfect addition to my puzzle game folder, there is one issue however that is a bit tedious, when I select one of the puzzle pieces and try to move it where my finger is does not sync up to where the image is, (as in I'm touching empty space and the piece that I'm moving is about a centimeter away from where my finger actually touches the screen). A mild issue but an issue nonetheless that dampens the pleasantness of the gameplay (this bug is especially irritating if you drag and drop the piece only to let go and find you didn't drag far enough to compensate for the extra centimeter of space and the piece defaults back to its start position).

I’m giving this game 1 star simply because of the significant battery drain, which I think the developers need to address. Even when set in HQ mode (go to settings in top left corner) this app drains 25% of my battery (iPhone 6s) in 5 minutes and killed my battery after playing for 20 minutes! I would like to know why and, more importantly for the app, would like to see it fixed. Otherwise, the game provides a great mental challenge and plays very smoothly. The graphics are calm and pleasing. The movement (rotation) of some pieces can be frustrating at first, but not overly bothersome after figuring out the “technique”. Overall, this simple game is a time-drain that is worth the $1.99. Unfortunately, is not worth the battery drain.
