Play Online: 2048
Developer: Gabriele Cirulle
Genre: Puzzle, Strategy
I believe there are billions of ways to form 2048, however, I figured out a general solution for myself to beat 2048. My winning rate is around 40-50% or so, however, it's not entirely foolproof strategy. I stick to the same strategy introduced here, learned some bad situations to avoid and with a bit of luck, I could manage to achieve 4096.
This game is actually not easy. Even with a sophisticated AI, the winning rate is not 100%, but 90%, according to the AI developer appeared on stackoverflow.
Here are some of my strategies and thought process of getting the winning number.
My Three-Golden Rules for 2048
- Arrow Restriction: Basically, use right, down & up only. Never swipe left.
- Always "fix" the 4th column.
- Always keep the 4th column sorted at all times.
- Black Zone: Fixing Area
- Grey Zone: Primary Working Area
- Brown Zone: Secondary Working Area
Note: Please refer to the picture above when needed, each box are given a number.
1. Is the 4th column fully sorted?
In my mind, I see the 4th column as the "Fixing Area". By fixing, I mean filling in the 4th column with tiles and they're permanently stuck to the column. The main reason is that you can avoid a junk piece coming into box 16 when you had to use the up key. So, always ensure that the 4th column of your board is filled with tiles at all times.
>> Once done, proceed to step 2.
2. Is the 4th column in a downwards ascending order?
Make sure to arrange the tiles in ascending order from top to bottom in 4th column now! The tile bearing with the highest value should always be at the bottom right corner of your board, box 16. The value in box 12 must be smaller than box 16, box 8 smaller than box 12, box 4 smaller than box 8. If one of the box breaks the ascending order, fix it.
>> Proceed to step 3 if success, otherwise jump to step 4.
3. Stack numbers around Primary Working Area and merge into box 4.
Logically, you should build numbers side by side. I mean you don't want to waste any unnecessary moves which might risk ending up in a really bad situation. Basically, I divide the 3rd column into two areas; "Primary Working Area" and "Secondary Working Area". Primary Working Area is the zone nearest to box 4, consist of box 3 and box 7. Your goal is to build numbers around box 3 and 7 which you eventually can collapse and merge into box 4.
>> If you manage to merge the numbers into box 4, skip to step 5. Or else, go to step 4.
No worries! This is where the Secondary Working Area comes to the rescue. Box 11 and 15 are your so-called "Secondary Working Area". Why? Because if your Primary Working Area is blocked or you accidentally merge a big value, just simply slide the tiles to secondary working area! This will make space for your Primary Working Area, which you can continue to build numbers and work towards merging into box 4.
Or, last resort! Build your numbers around the Secondary Working Area then collapse them into any boxes along 4th column. Do not panic if your board starts to fill up. There's a will, there's a way! Think flexibly and find shortcuts. Once you’ve done that, you’ll find your free space much more open again.
>> Proceed to step 5.
5. Can you collapse any number downwards at 4th column?
Saw any repeating numbers you can merge downwards along 4th column? Merge them. Tada! :P
>> Repeat from step 1. Otherwise can't merge, go back to step 2.
