2048 How To Solve

This video introduces three simple strategies I came up with for winning the 2048 game.1. Arrow restriction: use right you are solving essentially the same problem.By fixing, or filling in the 4th column (not the 4th row) with tiles, you can avoid a junk piece to come in to the tile[4][4] when you had to use the up key. Exception is when the tile-merging happens in the 4th column. In that case, avoid up and use down instead.[Some Additional Tips]- If you focus on building the 4th column, you'll learn how best to build the 3rd.- Advanced technique: left arrow (in my strategy) is useful to recover from the situation where the 4th column is unsorted. In that case, don't forget to "fix" the 3rd and 4th rows by filling them in. - Recovery tip: To recover from the situation like tile[3][4]=1024 and tile[4][4]=2, use arrows including Left and push 1024 into a different corner. Then do the "change-of-gravity" (change the arrow restriction accordingly).- Concentrate and think ahead. One small mistake can ruin the game especially in the later stage of the game.[Note on Chance of Winning]2048 is very hard. Even with a sophisticated AI with what's called "the iterative deepening depth first alpha-beta search" algorithm, the winning rate is not 100%, but 90%, according to the AI developer appeared on stackoverflow.With the strategy introduced in this video, my winning rate is like 10% or so. It's low but having some strategies is better than having anything at all. EDIT (Mar 17): My winning rate is now 30% given results from the past 10 consecutive games: 2048 x 3, 1024 x 3, 512 x 3, 256 x 1. I stick to the same strategy introduced here, but learned some bad situations to avoid.更多
