　　2048 game play strategy tips
　　1. The method of keeping the biggest one in one corner is feasible. Take the bottom right corner as an example, you need to pay attention to each time you press left and right to keep the fourth row full, and press up and down to keep the fourth column full. (Of course can phase out and still be able to keep the position of the corner can also be)
　　2, do not press the left. Then try to leave the largest number in the lower right corner.
　　3, the number to be added to move less (I am usually placed in the upper left corner, so it is safer, if the calculation ability is particularly strong, this does not matter), with low-level root to create a high-level root, and the root to have continuity. For example: when the number is added to 512, your chart should preferably have 256 (previously added using low-level roots), 128, 64, 32. This leaves more space after the numbers are added, so it is not easy to end the game. So this game is actually a game that relies on "preparation" to pass, meaning that you don't rush before putting together 512, but first put together the individual roots.
　　We can also use the following idea.
　　The first step: in order of number size (from high to low) will be 1024,512,256,128 four numbers on the side, these four numbers remain unchanged. (Explain the same as the above knowledge, the right click does not work.)
　　Step 2: in the remaining 3 * 3 square frame to construct 128, and to be close to the left of another 128
　　Step 3: 128 and the left column of 128 to touch into 256, 256 and then touch up, and has been touching 1024 has become 2048!
