Threes and 2048, there's a new logic game sweeping over our phones and browsers. Logical Cell brings us their new creation, Concentric Holic. Eliminate the color squares by placing the matching colors next to them. Once a layer of the square is removed the next color layer is active setting off a chain reaction. The premise sounds simple enough but it's anything but when you find chain reactions you didn't even spot tearing through your colors and leaving you stuck. All I can say is thank goodness for the Undo button.
Play a few levels and you'll find the only thing that will stop you from continuing is the lack of a solution, and even those who might not think logic is their thing will find themselves struggling to put this down. The undo button is a necessity as once you place a block you can't move it, which will lead to some frustrations as the desire to just slide it over to a new spot is great. It also increases difficulty, since it will remove the last block you placed. So in order to move one block, you may have to take off three before it, ruining your mental pattern. Still, the simplistic design and the amount of mental work it will take to get through the levels makes it all worth it and more. Pull on your sweat bands because this mental work out will get your brain into shape.
