SwipeBlocks LITE (Free) by tEXtOO.NEt is a puzzle color-matching game where you have to link as many pieces of the same color as possible before time runs out.
When you find blocks of the same color next to each other, run your finger from one to the other to link them. You’ll know they’re linked because they will have small white dots in the center.
You need only two blocks of the same color to be adjacent to form a link, but the more you link at the same time, the higher your score will be.
As you progress through the levels, you’ll find you have access to time bonuses and extra points which are really helpful in beating that speedy timer. You’ll also occasionally get the option to “shake the screen” to rearrange the pieces in case you’re struggling to find a solution.
You can save your progress, but that feature is available only in the full version which will cost you $0.99. The full version gets you more levels (there are 16 provided initially), and removes ads.
There are a lot of these matching-type puzzle games around, but this is the first of this type that I have seen. Its new and relatively unique challenge is a refreshing change of pace and you have the option of trying it out for free.
