Aqua blocks is known as a puzzle game much in the same vein as tetris where you can make your own line of blocks and choose whether you want them to be vertical or horizontal. The idea is to drag and drop them in just the right place so that they will all fit together perfectly. In the game, you will see three different shapes and this will help you make up your mind about where to put each one depending on its size and shape. But you also get something known as an aqua power which can help you remove any blocks that get in your way. To use it, all you need to do is tap on the power and it will go away. You want to place all of the blocks in the right place so that there will not be any space left by the time the game has ended. The more lines that you clear, the higher your score will get. You don't want to rely on the aqua power too much as the idea is really for you to get a better idea of where the blocks go so that you can put them in the right place. The best part is it's free, has no time limit and you don't even need internet to play it. It's also really easy to play and is fun for people of all ages. The only thing is it does require android 5.1 or higher to play.
