2 by 2 comes with a clean and tidy design, and the intece is so user friendly and the gameplay is so easy to learn. Speaking of easy-to-learn gameplay, you just need to find points with the same number and connect them vertically or horizontally. (Note that diagonal movement is now allowed). The larger the line you draw, the higher points will be rewarded and the higher you will reach. You have to start over when you are out of motions and there are no adjacent points with the same number to be connected. There are also some power-ups in this free puzzle game that can be useful when you are stuck and have no idea what to do next. Multiplier, Refresh Board and Destroy the Cell are the 3 power-ups available. You need to collect coins and spend them to use these power-ups. Puzzle match
