I've got a collection of apps like this on my phone - from Sudoku, Unblock me, Tetris, and so on. It's time to test this one out! My brain is a little rusty when it comes to remembering stuff, so the first levels of the game I played mostly had low scores. But chill out, you'll get the hang of it sooner. This is also a great game for people that want to kill time, or while waiting on something. A fast phase game that needs a little focus on a lower difficulty. When you go higher, you should check  your blocks and time unless you score under 3 stars. Great graphics for this kind of game and the UI is great too, easy to see and click on.
